Dot could be good one for investment. Heard about near which could be okey but i don't know about flow. Well I won't investment any of those. First I'll buy ether with large amount for secure investment. Then sol, matic as well asa bnb for my pick up. All of those have good prospective for future. Then i bet for doge and shiba with little money cause thus i can get a huge money if luck favourable in my side. Besides i will try some gaming and ai coins and some new altcoins with low amount cause 1m is huge money.
It is a very large amount of investment and I will not choose one coin if you invest in different coins it will be possible to get profit from all coins. BNB and eth are growing exponentially from matic. These are more profitable than other coins.
actually even 3 coins is not enough for me to invest for,instead i am looking for 5-10 different cryptocurrencies and aside from those you mentioned I also wanted to Buy Solana and Cardano , also never forget to put some in Bitcoin , actually bigger part in bitcoin.
