I know that the lists are good , and others are may say against those  but this is mine .Just make sure you know how to diversify those holdings of yours because if you made single mistake
then all of your funds will be gone so never to be greedy .

ETH
BNB
LTC
SOL
XMR
Yeah, typically all the top coins that I like to have but not all of them I have because I’m still waiting for some profits to flow on me so that I can invest into the others. I’d avoid hype coins and those that I haven’t done my research yet so with those, it’s an easy suggestion and simply saying to go with the top altcoins.
