If you have no doubt please to buy bitcoin currently, i can't make sure that bitcoin is going to rise or fall from days to tomorrow but if see the bitcoin back up from yesterday, unfortunately, i lack the capital investment for bitcoin
Buying Bitcoin now is the best time, specially if you are expecting a hard fork and split chain. The reason is that you just doubled your Bitcoin, one in Bitcoin Core chain and the other one to Bitcoin unlimited chain. There is no reason to dump and fear the hardfork. If ever it drops its price, new people will join in the community making the price to recover and eventually breaking the ATH.
