I bought a bunch BTC when it was $17000, then bought a bunch when it is $14000...then the price dropped until 2 days ago. I bought a bunch again when it was 6000ish...haha, now the price went up...so, really, when is it a good time to buy? When it dropped for a while and it rose a little bit, then drop again, then buy?
you should have known that,because you purchased tree times in different occasions so this means youre aware of market,theres no resourceful mind here that can have this idea unless old timer here..
But about when to buy?well buy everyday as long as you believe that the price will grow after buying,theres no real indicator because crypto is volatile
