you must do your own research before buying the coins and as you know YOVI coins is a ROM coin which means Rise Only Market
So the maximum for each sell order is 0.01 BTC and if the sell order already has 0.01 BTC then you must set a new price which is higher than that
i found this thread How Do I sell yovi at yobit ? and in that thread maybe you can know how to sell the YOVI
edit:
maybe you can see the info about ROM at yobit
This is Raise Only Market, sells are only allowed to be placed higher than the current lowest sell.
- max wall size: 0.01000001 btc
- max sell order size: 0.01000001 btc
- minimal step between new orders: 0.00000100
- max 2 open for sell allowed for ROM market
