Dude... You don't know much about Stamp.
I dont think you do if you cant even notice obvious wash trading. Maybe get some window wipers for your glasses.
If you can't see the cause and time when stamp, currently undergoing wash trades or not aside, recovered a substantial number of their previously lost clients, you're at least as clueless yourself.
Their exchange used to have massive large volume trades on a constant basis. It seems that they only started using wash trade bots post hack, once they realized they no longer have enough customers to create such large volumes and therefore they have resorted to artificial volume trading bots.
You are free to believe what you would like to but consumers should be made aware of this so they can make informed decisions before risking their money.
