It is true that most of those who have tried to earn bitcoins through trading, have done so through the exchange of cryptocurrencies, however it seems increasingly difficult to obtain good profits in this business in a market as unique as the crypto one.
That is why I would recommend to all those who know the technical bases of trading to try a more stable and predictable market than the Crypto market, and that is the Forex market, where what is exchanged are fiat coins.
And fortunately there are Forex brokers that allow trading with denomination in bitcoin, making deposits and withdrawals in Bitcoin or even trading cryptocurrencies as CFD.
The important thing is to look for alternatives, and this is one of them.
Thank you for your advice and view on this but I don't think it is easier in forex trading. Both of the market are highly risky and you should not there go into them without proper and adequate understand on how it works.
