What happened::
01/07/2020 I used Sudoku wallet to mix my coins, but after sending 0.48455333 BTC my wallet became unavailable. I sent a support request but received a reply only after I wrote on the forum.
Are you mean, can't access sudoku wallet using this key;
qAHXjQNV8TpmHMhZQgVcFQFf ?
As I know when open wallet you received
wallet key (qAHXjQNV8TpmHMhZQgVcFQFf) and
bitcoin address (where available to sending fund) together with a
private key. If you can't access using wallet key, you can access using the different wallet like electrum because you have a private key.
lets me make illustration your case,
17aiiGHwvZGaZ5jeXgbccLsbgFwcBwewsh > is this address you own private key, right? then you sending 0.48455333 BTC into sudoku wallet 12Czrsks5H3jtmVUqUnqZLW45xqX3Qq9SH where you have a private key too. actually wallet became unavailable then going to email support together with
wallet key. CMIWW
My last question, Are you push
Mix my coins! yet?
