Why do people continue to use this exchange for trading and storage? Yobit's risky practice of locking accounts and coins is well-documented here. Sending coins to Yobit is playing a risky dice, almost always in favor of the exchange keeping the coins.
For those who ignore the countless scam reports, I can suggest a few charities who accept bitcoins for a good cause. You would be doing this planet a greater favor by donating your coins to them. It's the exact same thing. When you send coins to Yobit's hot wallet you are donating your coins to this exchange.
Agreed. And since OP has confirmed that it's 1.5 BTC it's a huge amount of BTC to be trusting a random exchange in Russia(or is it even located there, now) that has an absolutely dreadful reputation of being consistently the worst place to trade your coins and has consistently the worst customer support out there.
Even though i'm sure you did nothing wrong, you should have been informed on yobit's shady activities.
Their environment basically is completely toxic, the entire exchange relies on pump and dump coins to operate and wallets are in constant maintenance mode. People's money is stuck in every way you can imagine. OP, if you don't get your money back or even if you do, learn your lesson and don't return with a new account.
