How could you be so sure that ETH has the potential of doing another 5X? ETH went quite high during the last pump also. If you think BTC has reached its potential, then ETH also did. It makes sense to invest in the small caps if you are after big gains but there are lots of them and choosing one is like throwing a dice. You mentioned BNB which is the 4th biggest coin. You think it can do another 5X?
No one can predict with certainty the potential that each crypto will receive, especially if it has been determined 5x and so on. The huge profit potential from BTC is indeed not the same when compared to newly launched coins, but the risks involved are definitely much greater in crypto than BTC. The dominance of BTC is undeniable, whatever movement in the market refers to the movement of BTC, even if ETH is the second largest domination of the market, it cannot be balanced with ETH.
