I initially considered this as well (still considering), but I am a bit reluctant - a decent mining rig can be quite expensive - and I keep hearing or stumbling myself upon both pros and cons.
Some of the cons:
- Bitcoin mining is now feasible only? using ASIC miners. They cost a lost and I can't find a reliable source to buy them (i.e warranty for hardware breaking down, etc.).
- Bitcoin prices are very volatile, so if they go down (even for a limited period - e.g. up to a few years) I would be stuck with (temporarily) unprofitable equipment.
- Ethereum (for example) is minable using GPU-s (less risky investment from my point of view) but I hear in the near future it will transition to proof of stake and not be minable anymore (correct me if i'm wrong)
