Actually, it's very easy to find out through the help of coinmarketcap where almost all the coins that already have strong fundamentals are all there, it's just for everyone to make their choice, very simple isn't it?
https://coinmarketcap.com/currencies/squid-game/If you visit the link above, you will see a notification from Coinmarketcap that tokens cannot be sold after you buy, I think this coin is worse, because I have invested in this coin and it's true, the coin cannot be sold due to other reasons from team members .
Some coins that have good fundamentals will also end in failure, for example YANU, the team only focused on the product and didn't care about the tokens they created, so the tokens were delisted from the exmarket exchange and it was a valuable experience for me in 2018.
