This can be a valid point but not a guarantee because over time the token eventually ends up being a scam, you remember FTX which even has its own exchange with quite large volumes and also how UST is also a token that harms many parties with its scandals, even the big exchanges themselves could end up being a scam. If you want to invest in tokens, you also have to be prepared for all possibilities, that's why keeping tokens or altcoins for too long will also increase our chances of getting scammed, even though there are altcoins that last a long time and continue to provide profits to their investors, but that is very rare.
