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?
There's no specific time or day when is the good time to buy bitcoin. But my suggestiuon is when you feel tha bitcoin [rice is very low so it is time for you to buy bitcoin. buy in a low price so if the bitcoin price again gets up your own bitcoin will affected it will rise too. In that case you can also earn a profit for you.
