I used yobit.net for a long time and never had any issues that were major except no support and a lot of features broke often.
Withdrawal wise no issues...
I put 5900 LTC into yobit to get the LCC fork because i knew it would do well and could make a flip to change my life significantly (it went up like 3-5x). Not only was the LCC buggy and wallet had issues, but when i went to take back my LTC I sent 3 ltc first to confirm no issues just a precaution, then sent the rest, and bam, nothing, cant find the address they gave me anywhere no txid info. They even banned my account for spamming the chat, and the thing is they have support but your lucky if they get back to you once and things like this they dont want to touch even.....
here is first ltc withdrawal no problem ...
I already had my issues with mt gox, i know yobit is not great but i also have made a lot with them and never had one problem with top5 coin withdrawals, new coins yes but not the main ones...
I filed a complaint with the trading comission and funny enough a friend of mine just got screwed out of a few btc over his pet messing with his computer but thats peanuts, i have no idea how to proceed and have lost everything except enough to cover maybe a few months of shelter food and trying to get a job back as a teacher after doing crypto mainly for last few years. Tried bitcoin talk as well, basically i need you guys to give me some input because i dont know wtf to do.
