I didn't have any problems with Yobit, but be aware of possible scams. Phishing attacks are frequent with growing popularity of crypto.
I rarely see people who are becoming victims by a phishing link of yobit but still traders or new comers must be aware of any possible copying tactics by lazy hackers. The whole thing about yobit is that many are complaining because of their slow response to query of their traders.
Not just with Yobit, be careful with any other exchange.
Include also other web wallets, they are also vulnerable and precious in the sight of hackers.
