After Robinhood Suicide, Crypto Exchanges Must Stop Acting Like Casinos: bitFlyer Exec - CoinDesk

Many exchanges were designed to encourage users to trade as frequently as possible, often with money they don’t have, and resembled casinos more than responsible trading platforms, said Joel Edgerton, chief operating officer at bitFlyer U.S.
“There are too many exchanges that are run like casinos and exploit their customers,” he said.
Edgerton spoke to CoinDesk just over a week after a 20-year-old student, Alexander Kearns, killed himself after falsely believing he had got himself into more than $700,000-worth of debt by trading complex options contracts on Robinhood – an app-based trading platform with a young, retail-oriented following.
It later came to light that the negative balance was a temporary phase in between contract execution – i.e. Kearns wasn’t actually in the red. But Robinhood has come under heavy criticism for allowing amateur traders to access such complex instruments without safeguards to avoid confusion and, in this case, tragedy.
Late last week, Robinhood announced a $250,000 donation to the American Foundation for Suicide Prevention and vowed to add safeguards to its platform, such as tightening eligibility requirements for complex options trades.

While Binance’s CEO Changpeng “CZ” Zhao said in response last week that his exchange already implemented a “Responsible Trading” feature, Edgerton, a former head of operations at the insurance arm of French bank BNP Paribas, said the exchange was trying to shield itself from further criticism.
“I would say CZ’s response was mercenary. He is using a kid’s death to pitch his company and Binance is actually part of the problem,” he explained. The platform gets users hooked and their anti-addiction policy “highlights the fact that they built the product to be addictive,” he said.

Any crypto exchange that offered 125x leverage indiscriminately – which Binance began offering in October – isn’t serious about customer protection, Edgerton continued. BitFlyer, which opened a U.S. office in 2017, says it already restricts access to leverage and can flag or even ban users that display troubling trading patterns. The Tokyo-based exchange ranks ninth globally, according to CoinGecko, and is the market leader in Japan.
It was reported last summer a Chinese bitcoin trader killed himself after a 100x position on derivatives exchange BitMEX was liquidated, a loss of about $16.4 million in a single trade. Around the same time, an anonymous student trader said he was having suicidal thoughts after losing thousands of dollars on several leveraged trades on the same platform.
Arthur Hayes, BitMEX’s CEO, has previously defended his business, arguing that in a free market, customers can always move onto other platforms if they worry about being exploited or defrauded.
When contacted by CoinDesk, Binance declined to comment. BitMEX hadn’t responded to a similar request by press time.

Cryptocurrency exchanges have more of a role to play in customer protection, Edgerton said. Regulators worldwide cap leverage for retail investors, both in crypto and in traditional assets, such as equities. Japan’s Financial Services Agency (FSA) halved maximum leverage down to two times the value of the deposit this year.
As such, there’s no reason an exchange should offer 100x leverage on top of highly volatile assets without first checking whether the investor knows what they are doing and that they have the income to cover that level of exposure, argued Edgerton.
“We have a responsibility to provide products that are suitable to our clients,” he added. The Robinhood suicide “is what happens when companies focus on tech and profits rather than doing the right thing for their customers.”

51% attacks are morally justifiable

In this short post I want to set out my case for the moral justifiability of 51% attacks against proof of work cryptocurrencies. In the past, a 51% attack was a theoretical construct that most people didn´t seem to think would be practically achievable or lucrative. This has now changed, as hashpower can be rented on sites like Nicehash and Mining Rig Rentals for a few hours at a time. The attack delivers the attacker two prominent opportunities:
-You can orphan blocks of ¨legitimate¨ miners. This essentially means that whatever work was produced by legitimate miners during your attack became worthless. Mine a secret chain of two hours worth of blocks, release it and you orphaned 2 hours worth of blocks by your competitors. By the time most of the miners have noticed their blocks were orphaned in an attack, their nodes will have been automatically mining on your own chain for a while and it will be too late for them to do anything about it. The amount of money they lost would be equivalent to the amount you had to spend to produce your chain. Because mining is an industry with tight margins, the economic impact on these miners can be very big. The cost may be sufficient in case of a very long attack, to persuade them to quit their endeavor and get a real job.
-The more important opportunity is that you´re able to double spend your coins. This is potentially, incredibly lucrative. How lucrative it is tends to depend primarily on the inflation rate of a cryptocurrency. A low inflation rate means relatively little ¨work¨ is done to maintain the security of the system. A high inflation rate on the other hand, turns the cryptocurrency into a very poor long-term investment. As a consequence, most cryptocurrencies face declining inflation rates, that delay the problem of their ultimately unsustainability into the future. The bank of international settlements explains this issue here.
When it comes to the moral justification of a 51% attack, we first have to ask ourselves why proof of work is morally unjustifiable. There are two main reasons for this:
-Proof of work has an enormous environmental impact, that ensures future generations will have to deal with the dramatic consequences of climate change. There is no proper justification for this environmental impact, as it delivers no clear benefits over existing payment systems other than the ability to carry out morally unjustifiable actions like blackmail.
-Proof of work is fundamentally unsustainable, because of the economic burden it places on participants in cryptocurrency schemes. Cryptocurrencies can´t produce wealth out of thin air. The people who get rich from a cryptocurrency becomes rich, due to the fact that other people step in later. In this sense we´re dealing with a pyramid scheme, but the difference from regular pyramid schemes lies in the fact that huge sums of wealth are not merely redistributed, but destroyed, to sustain the scheme. The cost of the work to sustain the scheme is bigger than you might expect, because the reality is that relatively little money has entered bitcoin. JP Morgan claims that for the crypto assets at large, a fiat amplifier of 117.5 is present, as a purported $2 billion in net inflow pushed Bitcoin’s market capitalization from $15 billion to $250 billion. You have to consider that the Digiconomist estimates that $2.6 billion dollar leaves the Bitcoin scheme on an annual basis, in the form of mining costs to sustain Bitcoin. The vast majority of retail customers who entered this scheme ended up losing money from it. In some cases this lead to suicides.
The fact that proof of work is morally unjustifiable doesn´t directly lead to a moral justification for a 51% attack. After all a sane society would use government intervention to eliminate the decentralized ponzi schemes that are cryptocurrencies. There are a few things that need to be considered however:
-Governments have so far failed in their responsibility to address the cryptocurrency schemes. Instead you tend to see officials insist that proof of work might suck and most cryptocurrency is a scam, but ¨blockchain technology¨ will somehow change the world for the better. Most libertarians who saw these schemes emerge insisted that it´s stupid to participate in them because the government would eventually ban them and round up the people who participated in them. This didn´t happen because of the logistical difficulty of suppressing these schemes (anyone with an internet connection can set one up) as well as the fact that suppressing them would lend credence to the anti-government anarcho-capitalist ideology on which these schemes are based. Goverments might say ¨these schemes facilitate crime, ruin the environment and redistribute wealth from naive individuals to scammers¨, but anarcho-capitalists would insist that governments have grown so tyrannical that they want to ban you from exchanging numbers on computers.
-Because cryptocurrency is fundamentally an online social arrangement, governments have very limited influence over the phenomenon. Binance seeks to become a stateless organization, not subject to the jurisdiction of any particular government. Just as with regular money laundering and tax evasion that hides in small nations that can earn huge sums of money by facilitating these practises, governments are dependent on the actions of individuals to address these practices. Whistleblowers released the panama papers and the tax evasion by German individuals through Swiss bank accounts. Through such individuals, the phenomenon could be properly addressed. In a similar manner, cryptocurrency schemes will need to be addressed through the actions of individuals who recognize the damage these schemes cause to the fabric of society.
-The very nature of a 51% attack means that it primarily punishes those who set up and facilitate the cryptocurrency scheme in the first place. The miners who pollute our environment to satiate their own greed are bankrupted by the fact that their blocks are orphaned. The exchange operators are bankrupted due to double-spend attacks against the scams that they facilitate. When this happens, the cryptocurrency in question should lose value, which then destroys the incentive to devote huge sums of electricity to it.
Finally, there´s the question of whether 51% attacks are viable as a response to cryptocurrency. There´s the obvious problem you run into, that the biggest and oldest scams are the most difficult to shut down. In addition, cryptocurrencies that fell victim to an attack tend to move towards a checkpoint system. However, there are a few things that need to be considered here:
-51% attacks against small cryptocurrencies might not have a huge impact, but their benefit is nonetheless apparent. Most of the new scams don´t require participants to mine, instead the new schemes generally depend on ¨staking¨. If people had not engage in 51% attacks, the environmental impact would have been even bigger now.
-51% attacks against currencies that implement checkpointing are not impossible, if the checkpoints are decentrally produced. What happens in that case is a chain split, as long as the hostile chain is released at the right time. This would mean that different exchanges may get stuck on different forks, which would still allow people to double spend their cryptocurrency.
-There are other attacks that can be used against proof of work cryptocurrencies. The most important one is the block withholding attack. It´s possible for people who dislike a cryptocurrency to join a pool and to start mining. However, whenever the miner finds a valid solution that would produce a block, he fails to share the solution with the pool. This costs money for the pool operator, but it can be lucrative for the actor if he also operates a competing pool himself. In the best case it leads to miners moving to his pool, which then potentially allows him to execute a 51% attack against the cryptocurrency.
-It´s possible to put up a 51% attack bounty, allowing others to do the work for you. This works as following. You make transaction A : 100 bitcoin to exchange X, for a fee of 0.001 BTC. Once this transaction has been included in a block, you immediately broadcast a conflicting transaction with another node: You´ŕe sending those 100 bitcoin to your own wallet, but you´re also including a 50 bitcoin fee for the miners. The miners now have a strong incentive to disregard the valid chain and to start mining a new chain on an older block that can still include your conflicting transaction. Provided that pool operators are rational economic agents, they should grab the opportunity.
-Selfish mining in combination with a Sybil attack allows someone to eclipse the rest of the network, while controlling less than 51% of the hashrate. Your malicious nodes will simply refuse to propagante blocks of your competitors, thereby giving you more time to release your own block. Selfish mining will always be possible with 33% of the hashrate and as far as I can tell there are no pathways known currently to make the scheme impossible for people with 25% of the hashrate. This potentially makes a 51% attacks lucrative without having to carry out double-spend attacks against exchanges. Although double spending is a form of theft, it´s not clear to me whether a selfish mining attack would get you into legal trouble or not.

Conclusion:

The dreaded 51% attack is a morally justifiable and potentially lucrative solution to the Nakamoto scheme.
