only invest in Bitcoin if you are going to keep trading but if you want to grow your portfolio there are some coins on my radar like examples WAVES, ETH, NEO, SOL, XRP.
I think XRP and Waves will not be the good choice to go through but it is better to put money on Eth,NEO and SOL .However its always good to decide to invest on crypto and it is better to choose the top ranked coin on the market which are more potential than the bottom coin .Remember just invest on potential project like eth ,ADA,SOL,DOT etc .You can also can earn passive from crypto.com and from NEXO as well but it is better to trade cause you can earn huge from trading if you put your investment for long term .One thing i just wanna remind you at the end that DYOR before investment .
