So, back when bitcoin was new-ish by suggestion from a friend. I started faucets and and tried mining with my computer; which was alright, and by the time that I stopped I had about $20 in coin and I left it there for a few years or so until coming back recently and seeing how much bitcoin is now and then regretting not keeping up with the faucets and mining. My little $20 that I had is now worth almost $250 USD.
Yest, those were good times. I also mined bitcoin using an old computer and then a few servers I had access to.
Is mining with the PC even a option anymore? Are faucets even worth it? What's the best way to get back into this with having literally no income to actually invest with?
Mining bitcoin using a computer or even a server farm now is meaningless. ASICs are orders of magnitude faster and the difficulty increased accordingly. However, it is possible to mine some altcoins using GPUs or even CPUs (Monero, for example). Faucets are not worth it, you can get more from airdrops here. It may be better to participate in signature campaigns here.
