there are so many altcoins listed on the exchange and of course it is difficult for us to analyze them one by one, but we can choose altcoin investments at the top at coinmarketcap, among them there are many altcoins that have been around for a long time and still exist today, and have healthy movements , in the sense of keeping abreast of the movement of bitcoin as the mother of all coins. let's just take the example of eth, bnb, matic, all three besides being safe to invest, will most likely provide better profits
Of course there's nothing wrong with what you're doing. You choose to invest in Altcoins that have clear potential for the future without wanting to take risks with other altcoins. I think it's the most appropriate method if we are hesitant to partake on unpopular altcoins.
The thing is that people who know what they are doing and sure about it could also be wrong and that would hurt them a lot. I personally believe that this strategy is one that could work, I believe that he is doing the right thing and that's my opinion, you think the same way and they thought the same way as well, so we all agree, but lets not forget that we could all be wrong as well.
There will be plenty of people who will only own bitcoin, and there will be plenty of people who will own some low cap high risk coins and make profit that way too, we wouldn't know which one would be the best, we just do what we think could bring us the most money and sometimes we are right, sometimes we are wrong.
