When ever I try to copy a bitcoin address , it automatically changes to a similar one but different
There is new information for me. I haven't yet heard anything about this before.
Maybe you put wrong address when sending.
I think he dont put a wrong address and i think he mean every time he copy and after paste the result of address are different
This is a virus that we need to check and prevent while we are dealing or sending bitcoin..
The solution for this for safety like other said backup all files password and private keys before you format the whole computer.. and i think someone are remoting hs computer..
