It may happen for other wallet. I man you may use other wallet for example, dogecoin, ethereum, litecoin and so on. Also you are saying no one has used your pc for last month but it might be used longer ago then last months. They may trace for a long period of times.
Hi! The problem is that I can assure you that for the last six months, and for the last year, and for 2 years, no one could use my computer except me, because it is under a password.
And please note, no one told me which accounts were used from my computer. No one has provided any evidence. And I am completely sure that this is my only account. At 100%.
Moreover, I think that if the real reason really was multiaccounting, they would have blocked the account and sent the deposit back, and here they don't allow me to withdraw my own funds, which once again indirectly confirms the scam. And we both (me and stake) knows that message about multiaccountin - it's lie.
