For me, trading in Bitcoin seems more risky and your revenue will be very volatile.
For those stocks traded long enough in the market, the movement tends to slow down, which means you earns money relative slow,
But I don't agree with idea that investing in Bitcoin is more profitable.
Because high profit always comes with high risk, and you earn a lot in this month but probably lose a lot after next price correction.
So, it's just trade-off between risk(volatility) and profit. Just be careful about what you choose.
