You're right. I didn't immediately see fee values in the tx explorer so I just assumed testnet transactions didn't have those. Thanks!

Today I took some time to mess around with the bit Python library (https://github.com/ofek/bit), which I find pretty easy to use. I have been wanting to do some Bitcoin programming for a while, soo I decided to create a simple web wallet to test creating and broadcasting transactions. I'm obviously using testnet for this.

I initially used a testnet faucet to send two transactions to a main address, 0.0005 and 0.0001 tBTC to get started. I used my code to check for this address' balance and got 0.0006, cool. I then proceeded to used my newly developed web wallet to send two transactions to another address, both with a value of 0.00001 tBTC. I immediately noticed the balance from my main address was off, showing me 0.000028 tBTC which to me makes no sense, it should have been something close to 0.00058. I used blockcypher to check on those transactions (which are unconfirmed, but I believe this is irrelevant) to make sure my code was ok. Sure enough, 0.00001 tBTC was sent twice to the correct address, but the change sent back to the sender address is way off. What exactly happened here?

The transactions:

Thanks in advance!

I've been brainstorming how to take the correct approach when it comes to developing a good bitcoin marketplace website. People like to make things overly complicated and I believe simplicity is key. In order to make it appealing to most people, building it on top of Tor won't do it. There's just no way your marketplace won't be associated to a dark market.

Another obvious issue is that, while there is a lot of incentive to sell things for bitcoin, buyers mostly aren't willing to spend it. There has to be an incentive, and I believe with a price correction (there is way too much hype right now) that might just happen.

Some might say there is no real necessity for a proper bitcoin marketplace right now. While I partly agree with that, it bugs me quite a little that most of these negotiations take place either here on on reddit.

Hey everyone! First time posting here. Lately I've become interested in studying bitcoin marketplaces, and have been looking at some use cases. I'm sure some of you have heard of OpenBazaar, but I would like to know how many people who post around here use their platform, and if not, why not?

I haven't used it and don't plan on doing so. I think they focus too much on privacy and anonymity, which is obviously of interest to a lot of people in the Bitcoin community, but with the growing increase of the currency doesn't really appeal to what you might now call the "average user". People who just want to buy/sell stuff for some BTC mostly don't want to download software to do so.

What are your thoughts? What would an ideal bitcoin marketplace look like to you?
