which is more easy to earn bitcoins? what can you suggest for me i only got low investment . and how can i earn high profit?
Easier to use faucets and get literally pennies for your work (if you can even earn that amount anymore considering the state of faucets and how they continue to decrease their reward sizes), but trading will get you so, so much more that it isn't even funny. It's a bit more challenging to make money since it is guess-and-check most of the time unless you find yourself as part of a pump n dump in-group scheme, but you will earn so much more off of just $1 in most instances than hours upon hours or working at faucets and trying to pinch the pennies so you can have something of value.
You will earn a high profit with trading, with some risk, faucets have no investment and low risk but extremely low rewards. It's all up to you.
I strongly agree on your opinion that, its easier to use faucets and get literally pennies for your work (if you can even earn that amount anymore considering the state of faucets and how they continue to decrease their reward sizes), but trading will get you so, so much more that it isn't even funny. And adding also my opinion that, it is easy to play faucet than trading, you don't need anything to start and you only need to spend a time to visit one by one the faucet websites but for now, I think it is not worth because the reward is not big. In addition, trading has far greater profits, but it is difficult for beginners, in trading it takes precision and patience in analyzing altcoin. then the person who has no knowledge of trading, impatient, and can not analyze altcoin then he will lose.
