What do you think about the following anonymization scheme:
1. 3 Wasabi wallets are created: Wasa1, Wasa2, Wasa3. Each runs over TOR.
2. The sum to be anonymized is sent to a TOR mixer, and comes out as 3 x 2 = 6 transactions sent to the 3 different Wasabi wallets (2 recipient addresses per wallet); the 3 wallet wallets receive different amounts and the transactions are spread over approximately 24 hours.
3. On each Wasabi wallet the funds then pass through Coinjoin.
4. 3 "standard" wallets (like Electrum) are created: StdWal1, StdWal2, StdWal3.
5. Then, from each Wasabi wallet, each amount resulting from a Coinjoin (about 0.1 BTC each, but each amount is different from others), is sent to the same "standard" wallet. Only UTXO resulting from Coinjoin are sent.
Wasa1 send the first coinjoin amount to StdWal1 in one transaction. Then the second coinjoin amount to the same wallet (= StdWal1) in one transaction. Etc.
Wasa2 send the first coinjoin amount to StdWal2 in one transaction. Then the second coinjoin amount to the same wallet (= StdWal2) in one transaction. Etc.
Same for Wasa3 and StdWal3.
6. On each standard wallet, BTC are now ready to be held or spent (without taking any particular precautions).
A. Is there a weakness somewhere (step 5 in particular)?
B. Can this scheme be reasonably improved (without making it too complicated or expensive)?
C. On a scale of 10, how anonymous would such a solution be?
Thank you in advance for your contribution
