Update to my situation. With the different computer i was able to log in (after a few attempts). I have now saved 90% of my balances to a different exchange. Maybe i was only a unlucky. I lost about 70% of my invests, but at least i could take out a small part from them.
If you meet similar problems, try with the another computer and a browser. YObit support should work better. After all i did not receive a single answer from them.
I am an user of YObit InvestBox. It offers daily 5% or even daily 10% for your invest. All you have to do is wait 24 hours and play DICE game for at least 5 times. You can cancel your invest at any time and call back your investments. I bought 0.1 BTC worth of LIZA coins. Under 12 hours my account was closed.
Now i keep on getting these errors (since 13.2.2018):
Invalid login or password.
You cannot log in now. Please try again later or contact our Support Team.
Temporarily disabled.
Now "funny" part is that i can not play DICE so i am not getting my daily payments. Price of the LIZA will be dropping 10-30% daily.
Please listen to my warning about this exchange!
This exchange can work well for a months with the small amount of money (under 1 ETH). Right after you start to trust them and raise your deposits, it is more likely that they will rob you.
This exchange need to be closed and blocked as soon as possible for our savety!
