To answer the question:
How are we going to be able to trade Factoids - will they be on crypto exchanges?
Shape Shift has already announced their plan to integrate Factoids after May 15th when the software sale is complete.
Shape shift is just a way to convert currencies not a trading exchange. What will determine the value of a factoid? The way I understand this is you want to keep the price of a entry credit to 1/10 of a penny and will create new factoids to keep this price at this level, so how will increased adoption increase the value of a factoid?
Thanks for your patience, I really want to understand this.
