We have too many coins in crypto space and I don't expect all of them to be needed in this world, many will die in time and only very few will be well recognized because of their real use cases.
I think I'll agree with you. The year 2020 will be very important for the entire crypto community. I would like to see what kind of scale stablecoins. In altcoins, I stopped believing and most likely they will break another bottom. I think that bitcoin will show itself again.
