I want to find a good Altcoin to invest in before the bull starts, also have a non-custodial exchange. This means, that we have complete control over our funds. If there is, please help convey it, because a lots of new altcoins was born every day.
Try not to focus only in Altcoin mate , because yeah there are good of them but also the best is bitcoin
so why just ask for altcoins? and also one thing to remember is that before altcoin , bitcoin will start to jump off so try to extend your investment coins.
maybe if you have 100% of funds, then try to consider at least 40% in the secured Bitcoin and then the remaining will be segregated to other alts.
in my opinion the best altcoin to accumulate at the moment are ETH, XRP and BNB, because I really believe if you will definitely get a big profits from investing in ETH, XRP and BNB, therefore now is the right time to buy and hold until the bullrun comes, because when the bullrun occurs, then you will definitely get a lot of profit.
but best if you are giving advises , make sure that you are also investors of those said coins and not just talking to your self without proving others.
