When the development of Wasabi Wallet finished and the first mainnet release was functioning, it was fascinating that now, without the need for a command line, we could coinjoin with just a few clicks using a light client.
Anyone could participate with any coin, without the system refusing their participation in any way. Wasabi has never discriminated against any coin’s origin. Anyone can participate.
But there were some limitations with the initial implementation of its coordinator. Inputs were registered at the same time using one request with Wasabi Wallet's coordinator. This is a privacy concern because this way, the coordinator knows when some coins are originating from the same wallet. Coins coinjoined this way were possible to link together on the input side but are still private on the output side (so long as the user did their due diligence with UTXO management).
This burden of heavy UTXO management is bad for the user experience because everyone must remember their coins, name them and then be wary of how they are spent.
Linkability is a problem everywhere. But with the latest development in Wasabi Wallet 2.0, many things have changed and privacy given to the user through the use of its tool is far superior to the original Wasabi Wallet.
With Wasabi Wallet 2.0, you need far fewer steps to coinjoin larger amounts. It also leaves much less bloat on the Bitcoin Blockchain when you are finished because you don't have to coinjoin again and again to increase your privacy and you don't have to rely on breaking down your initial transactions to special amounts just to take part in limited output coinjoins.
The previous requirement to have 0.1 BTC as minimum amount for coinjoin is no longer present within WabiSabi, everyone will now have access to a service that is affordable and easy to use to achieve good privacy. It is truly the pleb compatibility that is now here with WasbiSabi.
With WabiSabi it doesn't really matter where your coin originates from, you can merge without having to think twice about it. Of course, you can still put a tinfoil hat on and coinjoin with any strategy, but the automated process in the wallet should be fairly sufficient to give you the best privacy that Wasabi Wallet can give.
Strategies that the tinfoil hat users use are probably the best because if you are going to mix KYC'd coins first and then mix with other already mixed coins, then you can merge your coins without revealing that you have coins originating from somewhere else.
With the hard work and dedication of the bitcoiners working at Wasabi Wallet, I hope this company can continue to provide good privacy for every bitcoiner out there, wherever they may be. So once Wasabi Wallet 2.0 comes out, grab it and coinjoin the f*ck out of your bitcoin.
