It is possible for new coins to reach top 20 list.
Uniswap and Sushi are quite popular these days. I wonder if these coins will remain their position in the top 20 list.
this speculative assets
if they will grow in value, it is only for a short time
bitcoin and ethereum for them to be out of reach, because these coins are no fundamental basis.
they can enter the top 20 list but will not be long, they will be ousted.
