Go to:
https://blockchain.info/wallet/new
and set up a "wallet".  Costs you nothing and is totally anonymous.

Then go to:
http://bitcoinpyramid.com/r/7617

Make sure that your sponsor at the bottom of the page is #7617. If it's not, I'm not 
your sponsor and won't be able to help you. You can clear the cookies and browser  
then reload the page. 

Don't lose your Member ID and save your profile link so you can check your  
progress and make deposits from time to time.

Again,  this costs you nothing and is totally anonymous.

When I see you join below me, I'll send something to your deposit address  
to get you started. If you want more income than this you'll have to deposit 
some of your own and wait for those that follow your Referral Link to deposit 
below you. Display and post your Referal link wherever you can.  Although the 
pyramid will randomly assign someone under you occassionally it works better 
if you can get your friends to join in.  So social network!

When the $$ at bitcoinpyramid get large enough they send it back 
to the Blockchain wallet so keep a record of your ID and passwords.

I might add that there are only about 7k people signed up at this  
point- so that leaves 314 million people in the USA to go. 
Nothing to loose - every thing to gain.
