Do you think is is a well diversified portfolio or are there any coins in it that should be dropped and substituted.
I have voted for Ethereum and also Solana. SAND and also MATIC are also probably good choices.
Btw, have you invested in the first crypto? Bitcoin? In my opinion, the man investment is better in Bitcoin. Then, we can add more portfolios with some altcoins that actually have a bigger chance to rise up in the future and of course altcoins that have real and strong fundamentals and utility. Some altcoins that I mentioned above belong to this criteria.
But. why don't BNB? I think that BNB is also one of the worthy altcoins to invest in for the long term. We know the fundamentals and utility of this coins, this may have a big chance to rise up again as Ethereum did.
