A Shum is a person who buys new versions of phones as soon as they come out and disregard their perfectly fine old versions of the phone.... Usually people in their late teens and 20's, who want to look "cool" by having the newest versions of phones)
That Shum Dave just spent $300.00 on the new Galaxy phone that came out yesterday, although his old Galaxy still works just fine.

Should Have Used Monero.

What do the creators of WannaCry, Alexander Casez, Alexander Vinnik, Gal Vallerius, Bradley Anthony Stetkiw, Jian Zhang, Xiaobing Yan, and that group of Bitcoin hodlers who got kidnapped by thugs in Turkey have in common? They all SHUM.

Monero is a trustless cryptocurrency that is similar to bitcoin. Unlike bitcoin, it hides these aspects of every transaction from the public:

- who sent it
- who received it
- how much it was

This makes it ideal for anyone who wishes to transact privately.
Person one:

"did you hear about Joey? Apparently his doors kicked in and his face got slammed into the sidewalk because a bunch of nocoiner LEA found out he was using bitcoin to buy dried flowers on the darknet. The blockchain totally narc'd on him"

Person two:

"SHUM"
