I wouldn't advise investing into Bitcoin now. I am assuming that you don't really know much about it and most likely don't have any sort of Bitcoin wallet at the moment. It would be better if you learnt more about Bitcoin and then invested after segwit is engaged, the price is expected to drop anyway, so you would be saving yourself a couple more pennies. If you do however have a good understanding of Bitcoin and the upcoming fork, then now still isn't a good time, the price is just way too high.
