In the future there will be billions of dollars stored in Wallets, what if one day they decide to stop and shut down their services and transfer all the money to their own wallet and confirm the transactions and convert all of their coins(Bitcoin and any other Altcoins) to USD and disappear?
How can we get our money back? whom can we sue? how can we prove how much coins we had in their wallet?
It is possible to happen since coinbase is a centralised exchange. But I think, the owner of coinbase don't have mental disorder to do that because his name, reputation and securities are at risk when he will run out the money of the people.
If our money in cryptocurrency will totally lose, we are not compensated rather if you will lend your capital or savings in a bank, there is a chance that your money may return with due process of law.
