If someone had to start trading to build up their nest egg and had $30 to throw into the mix where would you put the money?
Since it is a small amount, I recommend you to invest into a coin that can offer you a lot of profit. I think for a reason that I want to invest that 30 usd to TRX. This coin is just keep on improving. And I continue to invest in this coin because I think this has a great potential.
Seriously, don't listen to anyone telling you about some coin like this. TRX even I have a little, but I would never tell anyone to invest in it if that was all the money they had in the world.
Build a nest egg with something like Bitcoin, but really, don't even think of putting a single cent into crypto unless you're willing to lose it. If you really want quick profits, you're better off gambling it.
