Be prepared.
This is a warning to all of you running after meme coins, even if they get listed on top exchanges it doesn't mean they will survive for long, or have you forgotten that many projects got delisted from exchanges after the ICO craze of 2017? The same thing will happen once a tough bear market starts, so many meme coins won't be able to cope with the situation and many exchanges will be forced to delist the tokens.
I do not think there is nothing to prepare for, delisting of tokens from exchanges will always take place; it is infact a constant K in the crypto currency world; altcoins token die every day, every hour and every minute, so ofcourse such tokens willl be deleted from exchanges to allow new tokens flourish. The warning should have been to encouraged every token investor to always monitor and follow the growth of their tokens so that they can always take profit, or exits loss before tokens get delisted from exchanges
NB: Exchanges are not forced to delete tokens, they have terms and conditions, failure of a token to comply for consecutive months = delist
