Lol, to what end? What is this collateral meant to insure? See red font above, you're not making any sense.

cowboyminer is suspect as of this point, so that does you 0 good.
So you sell and host 1st round, then cowboy hosts 2nd round?
But you have cowboys miners a collateral wtf sense does this make?
