but the difficult part is to convince the court to accept refunding you while you use an exchange and you have only Bitcoin deposits...
I want to believe that the judge will consult with some programming expert and that he can explain all the technical aspects of this issue, and probably the judge will decide in favor of the crypto investor... because okcoin assured its customers that they would have BCH, if okcoin had not promised anything, had not guaranteed anything then that crypto investor would have no reason to complain in court.
As public information indicates, on 1 August 2017, a hard fork of bitcoin was created, and there came bitcoin cash. As a result, the bitcoin ledger and the cryptocurrency split in two – Bitcoin and bitcoin cash. As promised in the announcement of OKCoin, at the time of the fork users holding bitcoin in the platform was also in possession of the same amount of bitcoin cash units.
it is enough that the judge see this part and realize how the hard fork works that at the same time will declare the crypto investor as the one who should receive his BCH. Now there's another point here. If the crypto investor had for example 1000 BTC it should get 1000 BCH, I do not see why the crypto investor asks for $ 25000 of compensation for his losses, he is converting crypto to fiat something I doubt the court will do ... because the Okcoin's promise was 1: 1. but that is my opinion, I am not a judge or a lawyer.
