I have been following Siacoin (SIA) for the last two weeks and it went up very fast, I read there webpage http://sia.tech/ I understood Sia will provide in data storage and in the future webhosting on the blockchain. So far they are still developing and they are checking software in ervery two days. But why are they so much up, I can't find that, there are like 26.000.000.000 coins already how can a project with that amount of coins be worth one dollar a coin for example, can someone explain that to me please.

I think LBRY is simulair to SIA or is that totally different? It would be great if an expert can tell me about these differences and give a forecast about the projects. Have a nice weekend everyone.
