I've got a call from scammer today.

Said I have 3.5 bitcoins in their Blockchain investment company from 7 years ago. (And the only way to retrieve it was to re-deposit 0.035 BTC to unlock my account)

I let him speak for minutes to waste as much of his time as I could.

Then I finally asked him how's his sleep. Considering he fills his days with scamming people...

He hung up. To be expected.

Sad story.
