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.
That's because most people just start "day trading" without knowing how to. If they studied TA and indicators for at least a few weeks (better months) before trading, they wouldn't die like flies in the market.
