If you’re not sure of the coins to invest your money in, then you should just invest in only bitcoin. When I started, bitcoin was the only coin I was investing my money in and it worked for me. I did that for some years without investing in any altcoins at all and it was working for me.

It hasn’t been long that I started to invest in a few altcoins, and if you’re to go for any of those altcoins, you should consider the top altcoins for now. You’re still new and you wouldn’t like to make a mistake you will regret later. So coins such as Bitcoin, Ethereum, Tron, and ADA would make a great choice , or you can go fully on bitcoin instead.
