The core question here is; what triggers you to invest?...for myself, I haven't figured out any tangible reason why I should invest, solely because I'm yet to understand the nooks and crannies of the market fully.
It is not hard to understand. Read about bitcoin halving, how people use to buy bitcoin more after halving. It may not be immediately after halving, it can be some months after. This is the reason to invest in bitcoin now, because halving will occur in 3 months time, likely in April. Bitcoin is an asset that it's value is increasing as its price is increasing.
