You can send specific sized amounts in a coinjoin using Wasabi's RPC interface -
https://docs.wasabiwallet.io/using-wasabi/RPC.html#payincoinjoinThe creation of small UTXOs from coinjoins allows you to avoid creating change outputs from coinjoins. These small UTXOs won't continue to be split and pile up over time though, small UTXOs will get consolidated back into bigger UTXOs as you continue to coinjoin.
With WabiSabi, users choose their own output amounts. Coordinators can set their own minimums and maximums (at the start of the round).
Thanks for your help.
So if I have some UTXOs from Coinbase and some from Kraken I should not combine these?
I have 0.15BTC right now and I'm not going to accumulate anymore. Most are from coinbase, but I have some from kraken, and P2P as well (not a lot)
How to I combine my UTXOs into one without someone being able to see that it is all connected to me?
