its not difficult to decided which best cryptocurrency that worth to buy today, moreover there are big discount now after market plumped. pick on top 20 and add some outside will give us best opportunity to earn profits. maybe at this moment LINK , ADA , BNB be one of them that be obligation in our portofolio.
Can't give any better advice than that.
However I'd add one thing to this - please consider sharing less than 15% of your portfolio to crypto currencies
it is extremely volatile at the moment
