I think that a lot of people are in your shoes as well. With a fork just around the corner, most likely, a lot of people are really scared and nervous about what they should do next. First step is to make sure that you are in control on your private keys. But back to the real question. Should you buy? To be honest, if you are asking for other people's opinions, you probably haven't done much research and are just looking for a quick and simple answer. Sorry to break it to you, but there is no such thing as a simple answer to this question. A lot of people will tell you a whole variety of things from, Bitcoin will crash to 500 dollars, or it will skyrocket to 5000 dollars. But what it really comes down to, is whether you believe in Bitcoin or not, if you do, it's still a good time to invest, if you don't, then don't invest. And remember, all investments are risk, there is no such thing as a safe investment. However, if you are looking to invest into altcoins, then it probably isn't the best time to invest as the price is quite high and many of the altcoins are pretty stable. I would just keep the amount that you have unless you are willing to invest more into Bitcoin.
