There are a lot of people, especially IT people, who try to make BTC sites, but in fact BTC users market do not demand that or BTC users market is not enough large for so many projects. Why they are wasting their time, what you guys think ?
If they fail, they've lost some time having fun with some coding.
If they didn't fail, they'll earn some easy extra money for quite some time.
So, really, why not?
And gained experience. Coding is a doing sport. You learn by building sites.
