Depend best for what? if you want profitable safe long term, go with BTC, eth. in my opinion XRP, and doge also safe these coin have bullish trend overall from theri inception.
but don't enter the market at this point, wait till the hype is over and market crash than you can enter on those coin.
(everyone know buy at low, sell at high, but most people don't do this, they buy cause of FOMO, and sell cause of fear)
If you want the best to make you rich, than put some money every month to invest in multiple new project, (mostly defi product) buy your token put in excel to remember them, do this every month.
But make sure to do research before you buy the token. even tough you only spare $100 or even $50 / month doing this. at some point one of the token will rise and give you decent profit. and at long term one of the is bound to rise to the moon, just dont' sell in the middle.
