Altcoins like ETH and BNB can secure your assets but if you talk about profits I think BNB and ETH will not give you 50% or even 100% profits like some new altcoins or meme coins. Because of that, I think you need to review what you want to get from your money in investing. Is it the security of your asset value or large profits.
This two coin are the potential coin in the market,because the investors in two coins was more in the number to the other altcoin.The comparison only for the altcoin and bitcoin had their own growing investor and supporting people was increased.So the investment made in this two coin will not make to feel to withdraw the funds from this two coin at the time of the bear run.Because the same price of this coin will increase when the market was changed to the bull run after some period of time.
