Well, it was said a bunch of times that HashOcean is yet another ponzi. I told a bunch of people how putting money there was suicidal no matter how much time the service has been running for. In fact, I specially told people to be wary of services like this when Bitcoin inevitably started rissing toward a new ATH. Now that we are on a uptrend, it was predictable that they would take the money and run.
i myself was of the view that hash Ocean will run away when they have lots of bitcoin deposits. also this time when the price of bitcoin is very high and people expected to withdraw their investments, they choose the best time to disappear.
