I have felt this same way for a few months now.. I have so many coins locked in wallets that no longer let you move the coins round...
Yobit is the number 1place for scam coins to end up and go to 1 sats.. I also have missing deposits from 3months ago of about 16000 doge and .01 of bitcoin... they will not and have not replied for any Support I have sent there way..
I was in their sig campaign up until a couple of weeks ago, and Yobit is where I did my trading, which wasn't much. I never had a problem with them as far as withdrawals, but all the while I kept hearing horror stories of the trollbox staff guy calling people faggots and so forth. They definitely have a customer service deficit. And because so little is known about who runs it over there (AFAIK), they appear to be very shady.
And yes, Yobit is where shitty coins go to be buried in the 1 sat graveyard. They give those turds away for free to suckers who claim them. That's more of a time-waster than a faucet.
