They don't have to *BUY* any coins. They already have them!
Why would would you as a builder go buy cheap plywood when you already have enough for the job? Sure, it's cheap plywood, but all the money you have to buy the cheap plywood is spoken for... to pay the construction guy's salaries for a while. What are you going to tell your contruction guys... sorry, I spent all your salaries on more cheap plywood?
You're missing the point, people are buying it below $10
to dump it for $20 next week. Keeping the $5 example, if GAW buys it today it costs $5, if they don't and someone else does they will have to buy the SAME coin for $20 next week.
Buy today: It costs GAW $5
and they can sell it next week for $20Don't buy today: someone buys it for $5 and sell it to GAW next week for $20, it costs GAW $20
So people are wondering why they aren't buying right now if there is a $20 floor...
