Hello,

I confirm the disclosed receiving address 3Q441kMPSEzPvw3Z7Eex4LM6USi3w8XK43 belongs the MCM.

I am sorry for the misunderstanding in email conversation, you are right and the minimum is 0.003 BTC, not 0.03 BTC. The numbers are very similar and I had a few other messages from users sending 0.0027 BTC and replied on muscle memory. Your transaction SHOULD BE and WAS processed - more on this below.

Because OP have not provided the LoG, I can rely only on the limited information to perform the analysis:

1. MCM received the 0.02699279 BTC on address 3Q441kMPSEzPvw3Z7Eex4LM6USi3w8XK43
2. OP claims the fee was set to 3%
3. OP claims there was ONE output address receiving 100% of the funds
4. Calculated output value for these parameters is 0.02593300 BTC ((0.02699279 * 97%) - 0.00025)
5. OP claim the delay was "default", about 2h 30m
6. MCM do not have a fixed "default" delay, rather randomize it from 2h 1m to 2h 16m
7. MCM knows the input transaction was confirmed in block 670969, at 10:40 UTC
8. MCM expects the output transaction to be confirmed no earlier than 12:40 UTC

Knowing the exact transaction amount, as well as an estimate time, we can search for the outgoing transaction.

I found the outgoing transaction matching all the criteria above:
- output amount is EXACTLY 0.02593300 BTC
- is confirmed not long after 17.02.2021 12:40 UTC
- the input address belongs to MCM

This proves MCM processed the transaction according to the settings disclosed by OP. The destination address in found transaction differs from the one OP sent vie email. I do not know the reason for this, had we have LoG we could confirm whether it was an user error, or a malicious actor's doing. Either way, MCM processed it as requested.

As I hope everyone can see, using the information provided by the OP I was able to find the output transaction associated with the input. Please treat these coins as connected with the input. Such analysis can be performed by anyone with basic blockchain knowledge, using only the information available in OP.

To avoid compromising your privacy, I strongly suggest using MULTIPLE destination addresses with random fee and delay. Transactions with only one destination are fairly easy to track when the fee is disclosed by the sender.
