Excellent prediction!
I have seen many tokens disappear from the market, the majority of them failed projects or scams. However, the number of projects & tokens continues to increase, at the moment I see more than 7,000 tokens on Coinmarketcap, and it is expected that this number will soon exceed 1000 if the DeFi projects continue to be borned as simple as today.
Competition is needed to grow, but maybe we only need about 300-500 tokens to be more than enough for the ecosystems in the future economy.
