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 bought BTC for high price, this is not problem for you ( don't sell BTC now, hold BTC because price will be rise soon)
6K USD good price for buying.
Also price today is good for buying too.
