Depends on what you think if you think it is good to buy you can invest your money right now. But you need to invest only some because until now is maybe decreased more or dump if many people will panic. But for sure bitcoin will pump again but not today but in thr future for sure.
Well it depends on what you prefer. I prefer to invest when the cost of investment is down. I do not mind holding for long then because it attains value in the end. But if you are looking for the rate at which value get added to the worth, you might not invest.
