Its never too late. If you want to buy, always make sure that youre buying at a trough and not at the peak for the forseeable future. For example, now btc price will increase until the fork, no doubt. However, after that for a few days, there will be a correction. If you pick yours up at that trough, hopefully the stablization will happen soon, and you will not lose anything, but may gain depending on this trend continuing.
