I think if you are not a big investor and have little amount of money then probably you should invest in a coin that is pricing low and you can get a bundle of the coins with just a few dollars.
Now I am not saying that you should invest your money in any coin out there but you should look for a coin that you see is performing well but is pricing low at the moment.
So one can invest a few dollars in there hold it for some time and when the price go surging, it can then be sold or even hold it some more time and wait for the prices to surge more.
Cryptos sometimes work in sort of crazy way, so you never know what can happen the next day.
This is not a financial advise. Just my views and thoughts.
