Because the price of bitcoin is currently rising and rising
yes, that's the main reason why we have to invest the money we have in the form of bitcoin. since the initial release of bitcoin until recently, the price of bitcoin is growing, and I think this will continue. so, maybe bitcoin can be an investment that quickly.
Bitcoin was always an investment since its inception and even in future it will act as an best investment tool so I think we are at good position to invest money in bitcoins as price will keep on growing as time passes by so invest in bitcoin till the price is not too high.
