NEO is a good choice for growth but don't expect anything significant in a week. If you hold on until october or november I believe you will be able to double or triple even. I have half my portfolio in NEO myself.

If you really only have $2.70 worth of crypto, go take a look at my post here where I have made a list of places you can go to get free crypto, some of which you can sell right away for more NEO and others will hit exchanges in a month or two probably.
I'll give you a follow! If you want, follow me back, I write mostly about crypto related stuff!
