I don't think there will be Yovi2. BlackSmith said that they will concentrate and support this one, by releasing a Yovi POS wallet next week, and on Monday updating rules to stop the sell wall abuse
It is hardly sell wall abuse. If a coin gets to 1 sat and people want to sell at 1 sat to get out then coins tend to pool up at 1 sat into a wall since they cannot sell it lower. That is not called sell wall abuse. In the Yovi case the lowest sell price is in effect like a 1 sat wall because people cannot sell it lower to get out. Each time the price goes up the 1 sat bottom moves up with the price. It is as if people are selling at 1 sat all the time.
