It's not a coin worth considering in the short term, like SLP and KEEP, both coins are down quite a lot from their previous price, for that if you choose to invest the Five coins you mentioned in the long term, I think it's a good move.
I also wonder why he didn't want to choose the other top five coins which in terms of volume and security are also very large so it's not a worry if invested in the long term.
I mean Bitcoin, Ethereum, BNB, Solana and Polkadot all of which are always excellent long term investments.
It seems to me that he is holding these coins or willing to buy better one. However, in the mentioned coins, I think the SLP is suitable for buying but it is for long-term investment. As we all know the supply of this coin is infinite. So this is the biggest problem to buy this coins.
