For me, BNB and ETH are the most trusted after BTC since they have some great development and working products to further improve their features and most importantly their market gain for the upcoming years. But of course, when it comes to investment you really need to give yourself some spare time to study what else they can offer in their next updates so that you can take some advantage to invest before it and make sure it is a long-term investment for these altcoins are not meant to be pumping easily, it took years for them to climb this high.
