I'm not asking for actual legal advice here, just some guidance based on what I'd like to do to make sure I'm thinking this through correctly. And to help me figure out what I might need to change.
So I gave up on mining recently, as it was nothing but a black hole for me in terms of cost effectiveness (way more electricity used than what I got back in BTC) and I can't afford any ASICs (or even used FPGAs). Instead, I'm thinking of treating my bitcoin wallet as a savings account, of sorts.
Basically, I'll be using Coinbase, or maybe CampBX through Dwolla, to put a few USD into BTC. Mostly I'll just be holding them in my main wallet that is not public, likely to even use a mixer service like what blockchain.info offers to make sure it's not directly linked to my public address for security. I'm thinking of keeping a smaller portion of the total at CampBX and try running a bot against it to see if I can get it to grow some, try to at least beat out the usual savings accounts at banks APR with it. I will only be taking money out of it in case of emergencies, and never in very large amounts when going USD<>BTC.
Most likely I'll be putting $10-$20 in per paycheck for now, maybe more if it turns out I can afford it after bills every month.
So my main concerns are around the FinCEN "guidance" and how this might interact with MTB/MSB laws. I'm pretty sure that I'll most likely not need to worry about that, and just make sure I keep track of amounts for when I cash out anything to USD so I can figure the capital gains correctly on my income tax returns.
Looking forward to the discussion and any feedback I may get on this.
