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.
