If you really want to choose only 4 or 5, you should choose btc, eth, eos, stellar and maybe cardano. These are very potential coins for me when bull comes.
I agree with the assets you choose, I myself now have 5 assets that you have, considering Bitcoin and Stellar which are my biggest investments. I believe this will be good in the future. until now I still hold the asset, even though it has been calculated, I have benefited.
