Yeah, 20 words is too much for me, my brain forgets words by the time I finish reading the sentence  Grin

Don't worry, I had to re-read it a few times to make sure it worked out. Smiley

May Bitcoin be touched by his Noodly Appendage
Have some fun with this:

If 7 billion people were to generate 1 million addresses every second for a million times the age of the universe we would not run out of addresses.

What's your last 1000000 for?

Looking at multiple sites that exchange Bitcoin, I noticed that a number of them offer a way to deposit Bitcoin in your account by sending it to some personalized Bitcoin address.

The method in which these are generated makes me think that there must be one or more such addresses for each account.

Are there any estimates as to how many accounts on these sites need to be created to consume any appreciable portion of the total number of addresses available?

It is recommended by Satoshi himself that every user should use a new address for every transaction.  Running out of addresses or ending up with the same address as someone else really isn't a concern.

2160 possible address hashes, 232 people on the planet. So each person could have 2128 addresses each. That's
100,000,000,000,000,000,000,000,000,000,000,000,000 addresses each. So even if you sign up to 1000's of these sites, you'll never make a dent.
