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?
The act of combining UTXOs is what connects all of these transactions together. So, if your current wallet software allows you to select the specific UTXOs for your transaction, you can send them to your coinjoin wallet one at a time, or send in groups (Coinbase group, Kraken group, P2P group).
Great that makes sense.
