Matic may consider for long term investing but you mentioned top coins ether, bnb, dot ada! I agree that those are best suggestions but Op already know about those and he wants to investing except those top coins because those are already grown a lot. That's why i suggested him "he cloud better consider Ftm & next" among the list of altcoins he mentioned as well as sandbox, cake & others
We can add several options to other altcoin choices but many investors stay on top coins for reasons of certainty of rising in the bullish period, because there is no guarantee that other altcoins can survive after the bear market passes and other factors due to the effect of the Luna crash so not many long-term investors believe coins other than BTC, ETH and BNB.
If we do research and analysis properly, we will find some potential projects, but indeed for long-term investment we must be more selective
and strict in choosing. Since not many projects are good for long term investments, most projects are only good for short term investments.
That's why in the end most people prefer to play it safe by buying top coins for long-term investments. Because top coins do have a good track
record, which usually always follows the movement of Bitcoin. So no matter how deep the price of top coins falls, it can always recover again,
so top coins are very good for long-term investments. I ended up doing the same, only entrusting top coins for long-term investments.
While the potential coins that are not included in the top coins, I usually only use it for short-term investments, which I will sell even if it only
makes a small profit. Because the risk is very high if holding coins that are not top coins, the possibility of surviving in a bear market is very small.
