Very nice, this is essentially at least a 2-3% bonus (depending on how much of your salary you need to convert into fiat, price declines, ect.) raise over your normal wage. This is also the taxes I was referring to as say you needed to sell $1,100 worth of bitcoin to cover your fiat related living expenses, but only "paid" $1,000 (via your wages) then you would owe taxes on that $100 in short term capital gains (assuming the below tax break would not apply to this)
Unless I create a localbitcoin sales company based in the Caymans and I draw a salary for my efforts. Then it is income which is subject to the $100k limit. But paying capital gains on $1k or so for the year is not that big of a deal (which I keep diligent records of when exchanging cash for bitcoins because I love the IRS and am a loyal citizen, etc.).
It sounds like you are above board regarding your bitcoin dealings and taxes. Based on what I have heard from people I have discussed bitcoin with in person, it seems that a lot of people are engaging in questionable tax practices when it comes to their bitcoin dealings which is not a smart idea nor is it good for "bitcoin's" reputation
