You can buy now. For bitcoin it is not a big price right now. But it will recover it's price very soon. If you buy in this time, hopefully you will be profitable. So don't late buy as possible for you. In every day buy little amount and gather it for big hitting.
i agree with you, many people out there say that the current bitcoin price is a relatively low price. so do I, I believe that although nowadays we buy bitcoin will not lose because bitcoin prices will continue to increase especially if we plan to hold in the long term.
