As per my knowledge, Some investors invest in bitcoin when the price reach to 20,000$ but now price is hardly more than 10000$.
Should they loose their money?
But still investors are invest in why ?
In any investment market, some investor make profits and some dont. Its depend on their strategy they use. But if want to make profits in bitcoin, i am believe holding for long term is good option because market will evolve and going bigger than before.
