Do you see your invested coins in the balances? Also have a look on order history to asure, that your coins are not hidden in an infilled order.
Then go to investbox. Wait, until the site loaded completely.
Ah and asure, that you are logged in.
Ok on investbox you have five areas. On the left and right site are Balances, markets, Chatbox and Yobit tweets. In the main field you have on left site a table of several investboxes. On the right hand are your investboxes.
Below is the history.
If that is empty, you are logged out or your investment wasnt executed. Then you should have your coins in balance or unfilled orders.
Nothing there, neither order history nor Balance. Unfortunately, My plan is also ended, someone already took my money from my investment plans as it not active anymore. I tried to sent tickets and PM to admins, and it has been almost a week but no response at all.
