It is very sad that this is happening. I was/am an early adopter and I though it was going to strive (honestly). But apparently not and I blame only one thing as part of the learning process for crypto culture. When you are launching a business... pilot it first (it's even free). Don't go live the first moment you find something.
On top of that you even have the best framework to do it... Blockchain!
Here is the email I have received.
A sad moment for some, but an essencial learning experience for others. I am sure BTCjam team will still be around and disrupt some other things on the same market segment.
