Well... I'm not a cryptocurrency analyst but under your "mentorship", I'd call it, i have learnt a lot.

When you say

use spare money

I always wondered if there's any money that is spare. But when you started to use the

invest what you can afford to lose

I caught the drift and it's been working.

The growth of Some cryptocurrencies are sometimes based on speculations and that's why we always end up using the "had i known" phrase. But we'd invest nonetheless, with the money we can afford to lose.

Thanks for sharing.
