So you think when they answer
They won't answer, if you look at the FAQ:
https://block.io/faqSee:
I forgot my Secret PIN. Can you get my coins for me, please?
When you signed up, we asked you to save your Secret Mnemonic. Do you have this?
If yes, go to Settings, enter the Secret Mnemonic (ignore the Secret PIN field), and then your new Secret PIN, confirm your new Secret PIN, and click 'Change Secret PIN.' This step will also generate a new Secret Mnemonic -- make sure to write this new Mnemonic down!
If you do not have your Secret Mnemonic, we cannot help at all. We do not maintain access to your coins -- only you can access these once you remember your Secret PIN or Secret Mnemonic. You can always confirm your coins are in their respective addresses using any third-party Blockchain Explorer, including SoChain.
