The 2018 Bitcoin Bomb Threats refers to a series of emails sent to various locations throughout the English-speaking world demanding $20,000 in BitCoin or a bomb in that location would be detonated. Authorities have since determined that the emails were a hoax.

Subject: Do not waste your time

Hello. My man hid an explosive device (Hexogen) in the building where your business is conducted. My mercenary assembled the explosive device according to my guide. It has small dimensions and it is covered up very carefully, it is impossible to damage the building structure by my bomb, but in the case of its detonation there will be many victims.
My recruited person keeps the area under the control. If any unusual behavioror cop is noticed he will power the bomb.
I can call off my man if you make a transfer. 20.000 dollars is the cost for your life and business. Pay it to me in BTC and I warrant that I will withdraw my man and the device won't detonate. But do not try to cheat- my guarantee will become valid only after 3 confirmations in blockchain network.

My payment details (Bitcoin address): (REMOVED)

You must solve problems with the transaction by the end of the workday, if you are late with the money the device will detonate.
Nothing personal this is just a business, if you don’t transfer me the bitcoins and a bomb explodes, next time other companies will send me more money, because this is not a one-time action.
For my safety, I will no longer log into this email. I check my address every forty min and if I receive the payment I will order my person to get away.

If the explosive device detonates and the authorities see this letter:
We are not terrorists and dont assume any liability for explosions in other places.
