I would suggest that you find out as much as possible before investing so that you invest based on sound knowledge.bitcoin has come a  long way from where it started in the beginning and has tremendously gone up in  value  in a considerable  short period  of time. of course now it  is going down after a steep climb, but  this is the  nature of this type of investment. I would suggest  that you  buy  and hold  until the market goes up again. it is now a good time to buy since prices are cheaper and then hold on to it for a few years before you start to sell.
