What are these people basing this on?

Math, Common Sense, and History say that a merchant will dump crypto as soon as they get it. Even a small (~$5,000/day) merchant would drive the price of XPY down an extra decimal place or two every day. There has to be liquidity (Buy Bid) depth enough to absorb a merchant or it simply does not work. XPY is no where near being able to support real merchants. "
Somebody" told these idiots that merchants accepting XPY will instantly drive the price up and they never stopped to think about the way it actually works.
