digibyte, litecoin, zcsh
These are the three altcoins I think I choose to remain if I want to eliminate most of them from your wallet.
And if you sell those that have been eliminated, I advise you to buy bitcoin. Your portfolio will now be consists of quality cryptos than quantity. It is a no-brainer tip to have bitcoin in your wallet or I think you already do.
This. Why not just sell those shitcoins in your portolio and consolidate it with bitcoin?
We are already in a bull run and definitely wouldn't hurt if you invest as there are huge chance to make a profit next year? And as I have learn in accounting, it's better to have a couple of banks accounts so that it's easy to manage, so that's also applicable in crypto, just a couple of wallets to maintain but with quality crypto in it.
It is not yet too late to sell them for bitcoin.
This might be the reason why op is asking this question. He's ready to remove all of the other unnecessary coins in his wallet and want to hold those few but good coins.
You will have the advantage op if you have bitcoin and those coins that I haven't included are gone. It is still your portfolio, you are the one to decide it.
