Let me get this straight.... You got some free things, then you didn't get some free things...

How is this a scam?  Just roll with it!  You don't even have to carry "it" around, it doesn't weigh anything, you don't have to feed it, and it doesn't make any rude noises or smells.

You don't even have to value it, you can just throw it away.

Seriously, if I play word-association with crypto, "Filthy Lucre" and "Rapacious Avarice" are the first thing that come to mind.

PM me an address and I'll toss you some.  I want something in return though, because who ever heard of getting something for free.

Stand in front of a mirror and (try to) say...

"The business in bismuth was brisk on the isthmus."

I will send you ten miracles for every time you can without spitting out your tongue.
