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.
in this case nowday Ethereum can take precedence since ETF is incoming its only matter of time, we know how bullish bitcoin is when ETF gets approved the price literally jumping and the sentiment is good moving forwards i will expect the same with ethereum except though maybe at lesser scale the price might jump but probably won't affect other altcoin or at least only affect L2 since we know etheruem itself is an altcoin.
but if it were to be approved of ETF then it almost instantly means quick profit for those that holds.
on the other hand though there are altcoin season that was expected to be coming by many people out there, im sure it will be something big in the future.
after all seeing past cycle, after every bitcoin bullish there is altcoin season.
