I have come to the conclusion that all of crypto to include bitcoin from the legal aspect is no different than MMO money.
Lets take a popular MMO such as SWG back in the day. Sony closes the company I lost all my credits... Lets say I did RMT to get this money and buy my virtual goods. Do I have a legal leg to stand on in suing sony for the return of the value of my virtual goods they took?
Lately there have been some interesting thefts in the space huge amounts of money taken. With the precedent set by Ethereum and of course amongst lesser known coins. All such thefts can simply be fixed with a hard fork returning all goods to their rightful owners. This makes the Bitcoin Foundation and developers liable in my opinion for not fixing the flaw in their software.
I think in legal terms we are in the minds of the law trading virtual goods no different than an MMO. I think anyone could stage that as a defense towards any wrong doing. I think any game manufacturer would fight such precedent... But with no definition of how to define it legally as a currency and with the unlimited amounts of variations... Who decides what is vapor, what is virtual goods, what is virtual currency. By denying one you make precedence for the other and vice versa.
My hypothesis decentralized crypto is going to die and when it does it will be quick.
Sadly over the last few years the only way for crypto to live is for centralization and regulation to control it. Which also destroys it.
