Few month ago I did believe in Ethereum but I start talk with people who work in this sphere and I did understand, that ETH it's worst, what can happend with crypto world
The ethereum is a good currency. Its fall is due to the fact that too many ICO projects are created on its base. Too much dumping.
In any case, the price of the BONA token will not depend on the Etherium. Only from the dollar. So no reasons to worry about that.
