I'm sure the paypro team and instant-bitcoins are buying them up
I also think the same, if this is what they are doing it would be easier for them to get the price back to 3k sat + and have a big supply of coins to sell on the site.
Sell at 4k sat = 2.5k guaranteed back to the customer + 1.5k which could go into buy walls on market who knows?
Hope to hear more about this.
if they buy up a majority of coins, they can dictate the price so long as they have the infrastructure in place. that is the real development here. the fiat-exchange infrastructure.
