Any alt coin suggestion expect ada.In my point of view of ada still can't surpass ETH in the smart contract field and even if they can make it will be hard to be replace existing eth smart contract eco system.Moreover late coming project like sol even surpassing to ada,all things ada have is the loyal user base and nothing special things in tech
Why don't you look at the top gainers on an exchange platform and the top altcoins on coinmarketcap or coingecko? You can find a lot of altcoins that are worth investing in. I don't want to invest in other cryptocurrencies that are now highly stable due to no advancements or updates in the project. Right now, I'm only looking forward to BNB, ADA, BTC, and ETH, as well as certain shitcoins that provide me easy double or triple money.
