So today I lost money on a transaction. This guy I was dealing with asked for my bitcoin address. I of course copy and pasted my bitcoin address and sent it to him. He sent me a screenshot of me preparing to send me my funds, i confirmed the amount but wasn't able to confirm the address because I expected him to copy and paste what I copy and pasted. I wondered why the funds didnt arrive yet, I double checked the address only to see that the address he sent the btc to was identical to mine, except for 1 letter (instead of a p there was a q)
Now my question, is it possible to create an address similar to mine, but change 1 letter/number?
