If you've bought it with your own money, then it might not be the best place to sell, also you are a newbie (me tooo..
), so you are basically wasting your time and energy... may be you can try giftcard marketplace, sell the card, then buy BTC for $10 in any btc market, coinbase..etc...its not a big deal...
I agree with you. I think this shows one of the weak points of Bitcoin: lack of trust. It's hard to trust somebody you don't know online. I really like the idea of PayIvy and being able to sell goods with no hassle, as opposed to eBay and Amazon, but I see now that there are some drawbacks.
As for the btc markets you talk about, there are 3 types:
1) Offer very bad exchange rate or charge commission.
2) Require massive documentation / linking bank accounts / etc. Not worth the effort for $10.
3) Require me to physically meet with someone in person (i.e. localbitcoins).
Even 3) is hard to do for small amounts as few people are willing to waste their time. I will have to go with 3) now, as it is the most feasible solution. Normally I would just buy a higher amount which would make it easier, but at the current price of Bitcoin I feel like it may not be a good time to go long.
