The buyer wasn't manipulating the market. He collects the names and isn't interested in selling them. So there is now less supply. Demand usually follows. In fact, now that these names are gone, you can't get a 3-letter name when they drop any more. They are instantly snapped up.
But ohh.............when those renewal fee's come due.......yes they will drop but into someone elses hand and the circle continues......................... :-D
now elequa spend probably $50k at 3 letter .biz and .info
And if he is going to renew them, every year it will be $50k if he does not intend to make revenue with them...
