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.
I think I can live peacefully with that amount of investment, look for something clear with the smallest risk and Bitcoin and ethers are the choices, while for altcocks, of course, they have potential. But I agree to share several investment options so that the profits obtained are maximized.
Potential altcoins include BNB, SOL, and Matic if you want to add them, but you can search and research on CMC to find a suitable choice. What is certain is that with large funds there will be many choices that can be made.
