Sure, online is much less of a hassle, but it's still a little 
time to sign up and administer.  Is that much of Ali's time worth 
spending for at least three donations, likely more?  I bet it 
would be.

I'm by no means steeped in the tech, but it's pretty 
straightforward to understand the broad strokes.  It's just a 
giant distributed ledger with some crypto to keep it secure and 
hashing to avoid double-counting, ie the duplication you're 
worried about.  But ultimately that doesn't really matter, as 
almost nobody knows how Dollars or other local currencies are 
created or what makes them tough to copy either. ;)

All that matters for a currency is that many buyers and sellers 
will accept it, or at least exchange it quickly and easily for 
your currency of choice, and bitcoin certainly passes that bar.
