I do not think there will be an end to it happening in the market. There are tens of thousands of trading platforms operating in the market, they are ready to serve you anytime. However, reputable exchanges, high liquidity are always the first choice of users. Be careful of scammers.
All such exchanges will sooner or later face huge liquidity problems, due to the fact that most of the coins will fall in price, which by itself will lead to avalanche-like withdrawals of money from the platform by users.
The only thing that exchanges can do is reduce the number of pairs to meet liquidity, which in the end will lead to the closure of weak little useful exchanges.
