When btc is very volatile as for these days, i tend to daytrade and buy low and sell higher with a bit of profit each time.
But whenever it goes lower I buy and not selling because want to sell at even higher prices later. I don't believe in day trading because most of the time people lose money.
Knowing that btc already set that record then definitely it can set another record soon too, we just need to have some patience and learn how to believe that it can still grow in time,
Thats how bitcoin goes anyway, buy more now.
