Depends what you mean really. If you're just talking about bitcoin mining then no, it is definitely not worth it to become a full time bitcoin miner simply because the difficulty has skyrocketed and it has become so unprofitable that you'll probably be giving money to keep your mining rigs functional. Unless you can have a large operation base as well as dirt cheap electricity, don't even think about bitocin mining.

If you just want to work for bitcoins then i would say it's a good idea. However there is little difference between that and working for fiat and then converting these fiat dollars into bitcoin in my opinion.

If you have a skill to offer for a bitcoin based company, by all mean sgo for it. In fact that's my dream career
