Bitcoin mining is profitable, if you do it yourself with your own setups, avoid cloud mining if possible, its hard to get a good return on those.
Bitcoin mining is profitable, but everyone cannot involve into the mining process. It requires high skill as well capital investment to setup a good mining farm. Some countries allow it as a legal and in some countries it has got strict regulations, so people used to mine it small scale farms within home.
I would never come up to understanding why having a mining farm is illegal while there are tons of people tapping on other people's electricity. Having a huge mining farm is totally legal because you're basically just powering up tons of devices all at the same time. That means more electricity consumption, and that means more tax for the government to collect. Casinos are an example of something that should have been banned for a long time already but haven't because the government collect pretty decent tax from them.
