Not sure why anyone would pay an extra 10% when they could just mix their coins for a 1-2% fee on a more TRUSTED website/service. Not trashing, just saying. Also, it's not 10x better than tumbling because any old fool can go on Genesis mining and get some "fresh" coins themself lol
I could be anything and I can't prove otherwise. The only thing that someone could check are my posts etc.
But let me clarify this. 10% isn't much. There is no counterparty risk, if an escrow is setup properly. All the mixers have a high counterparty risk and they are very traceable. Also, who the heck has told you that those mixers are not compromised??? Who said that the owners either gave in or were agents from the beginning. Also mixing with 1-2% is almost ridiculous.
Think of it this way. Only the amount of time you need to spend to save that 10%, by tumbling again and again (if you wanna do it properly), waiting for some of the coins to sit somewhere etc isn't efficient. If you want to tumble coins properly, you need to wait for at least 1-2 days.
As mentioned above, let's say that within a day x amount of people used a tumbler. Then the agents will know about all the inputs and outputs, except of some tumblers, who hold your coins for longer (with high counterparty risk). They can form profiles of how you do things etc.
Fungibility is a problem in bitcoin and will keep being one. Bitcoin is nowhere near cash atm. Monero and Dash might be, bitcoin isn't.
Anyways, I am not trying to mask anyone. Some people might have big plans for bitcoins and might want to HODL. These people might want to have fresh coins sitting in their addresses, without anyone knowing where they got them from or even that they have any coins. Finally, think of you receiving some coins by someone, without knowing where did that guy get his coins from. Then you try to cash your coins out from an exchange and that exchange freezes your funds. It has been done in the past and it will happen more frequently for sure.
