Pretty tough one, because we've had lots of buzz around some cryptocurrencies in the past and they disappoint.

Here's my pick:

1. BNB. I think Binance is a major player in the crypto space and they can leverage on their extensive userbase to do really great things with unique usecases for BNB. Something a lot of crypto projects don't have.

2. WRX: Sure. Another exchange coin. WazirX was recently purchased by Binance and they're in a good position to make some really good moves. Especially so because the government of India greenlighted cryptocurrencies about a few weeks ago.

3. Beam: A real privacy coin that actually works and is 100% private at protocol level. Not some BS coated with a lot of codes to make it Bulky. Pretty good for businesses too. It has a feature called Auditability, where a user can decide to show transaction history to relevant authorities. There's atomic swap as well.

I'll advise one more, because it's obvious: Eth, because 2.0 will allow you stake it, and DEFI is the rave.

PS: I'm pretty sure there's a lot of great cryptocurrencies put there. These are just the ones I know about for now.

For the percentage, I'd probably hold more BNB, then some extra Beams than I would hold Wrx. So, BNB >> Beam >> Wrx for me.
