I hope you do not expect people to include BFG in the three cryptos to build our portfolio 

Anyways, i will go with BTC, ETH and maybe SOL, i am not sure if i will be only having SOL as the third crypto, rather it can be multiple altcoins that i would like to include in my portfolio but it will be like 60% BTC, 20% ETH and 20% other promising or trending altcoins. We have seen altcoins going to very low levels and therefore i think the exposure to altcoins should be minimum in our portfolio.
