$2000 amount is good , you can invest your money to ethereum and ripple which is potential coin. You can invest also the newly launched ICO but make sure you already make a search about the project to know if it's scam or legit. Depends to you where you invest your money.
I will support your advice on investing in Ethereum. He fell heavily in value and it makes sense to invest in it. Ripple, on the contrary, increased in price and now it is too late to invest in it.
