I want to generate a constant monthly gain. Is it possible to do this by bitcoin trading? So, can I just do this by dealing with BTC trading?
Are there any people among us who can make a living by trading in BTC?
No. It is not possible to have fixed monthly income/profit with trading. Because the prices are changing continuously so there's no assurance that you can earn fixed. There are people who are making trading as their main source but it is better to have some other way.
Yes, it is very impossible to have a stable income with bitcoin because btc is unstable too. So we need to earn more and invest more to gain a big profit.
