Stick with reputable ones. I think I have said that so many times here in this section. Ethereum is a good choice but IMO only as an asset right now because the fees are damn high even when they changed to POS.
I don't doubt BNB too, Binance coin even if they are being cornered by SEC. Soon the truth will come out and it might boost the value of that coin more if they can overcome this challenge that had been fired to them.
I also bought CRO before, Crypto.com cryptocurrency Cronos. I think they will stay for a long time and based on how they market their business it will surely be one of the important coins in the market as time flies by. For now, there is really not much movement but it's good when we talk about consistency.
I agree that focusing on already established cryptocurrencies is the easy way out of this dilemma. However that'll mean no space for innovation and introduction of newer ideas. What I think we need is newer projects ready to build and improve on the groundwork already laid by the big guys. Rare, but they definitely exist. One project I'd use as an example of this is AITECH. Whilst focusing on real world usecases and a product that capitalizes on the latest trend- AI, they've managed to gather a committed community with their listing on thriving exchanges like Bitget. That's pretty smart, solid and also entertaining to me.
