Diversification isn't the best strategy, but it's the most outstanding. Why not share funds amongst 3-4 coins, you've done indepth research about, and have a resounding conviction that no matter any temporary downtrend, you're more than certain there's a boom around the corner. Chromia's $CHR, $DODGE & Stellar's $XRM is it for me.

Especially Chromia, risk of it failing in my opinion is very low, Chromia isn't focused on one aspect of the blockchain, but diversifies its technology towards influencing the decentralized applications, blockchain gaming, and even real estates. $CHR is definitely my ride or die.
