Would be grateful if you had shared the experience if any & how such services exactly operate the procedure?
In addition to their Trustpilot page
[given by Slow death], Ratimov did post a link to someone reviewing
[among other services] their services
[a bit old but a detailed one [you have to scroll down to the middle part]]...
- Seeing that they have so many negative reviews, I don't think much has changed since Coinsutra's review so I would advise going over to Ratimov's thread and look for an alternative instead.
