some time ago i use faucets now no more,mining on my country is out of question,so i do some surveys that pays in bitcoin and i partecipated at alt coins ico that i change for bitcoins,i also do some little sport bets
with surveys you will never be able to earn decent money, not even talking about even less paid stuff like faucets, so it is just a waste of time, while betting on sports might be really risky.
Trading
Gambling
Signature campaign
Offering services
These are the most common and most popular ways of earning bitcoins but first 2 options are bit risky and you can jump into only if you can afford to take risk as the results will not be in your favor every time so enter at your own risk.
you are right that those 2 are kinda risky, but trading can give you the most profit out of them all, signature campaigns and services (unless you are some kind of a professional) won't allow you to make a living.
For me I just invest in cloud mining on genesis mining, it seems to be a legit company that offers honest services not just another hyip scheme, that's why in a longer run it allows me to make big money without even doing anything.
