It depends on how much these $ 5,000 are from your total savings. Do not forget that the risks on this market are higher than on the traditional financial market.

First make a good research, and only then start investing. I would not invest all my savings only in bitcoin. To diversify the portfolio, I would also buy altcoins in such a way that only 70% of my investment was spent on bitcoin and other 30% - on 3-5 different alts.
