I didn’t actually like invest million on Doller in altcoins. it is too much risky. For my part, I will never invest millions of dollars in cryptocurrency. I will invest 90% of my fund in physical business like any mills industrys, it sectors etc and rest 10% i will invest on Bitcoin, BNB, ETH, ADA, DOT, MATIC, TRX, LTC, XRP, ENJ
Very wise decision to invest in real assets, but we are here assuming to invest $1m to fully crypto, but the investment coins list is very good but I will ignore LTC, XRP, DOT and ENJ from your list, so the rest of the coins are better rather than having to add more altcoins that may not have long term potential.
