With new interest in BTC, I see a lot of so-called "latecomers" who feel they are late to the party and have missed the boat.
I want to tell them that the party is just starting.
I want to tell them that the boat is just sailing.
 
That their 0.1 BTC makes them so rare as to be among the top 0.xxxxXX% as far as bitcoin ownership is concerned.
That, if bitcoin becomes the world's currency, their amazing secret to untold riches is simply to hold on to that 0.1 BTC.

So, here goes:

Now, let me translate this to top X%, assuming a world population of 7e9.

Do you own "JUST 0.1 BTC"?  CONGRATS! You are among the TOP 0.004%!!
  By all means, hold on to those 0.1 BTC, and maybe, just maybe, untold riches await you!

Do you own 1 BTC? CONGRATS! You are among the TOP 0.003%.

Do you own 10 BTC? CONGRATS! You are among the TOP 0.001%.

Do you own 100 BTC? CONGRATS! You are among the TOP 0.0002%

Do you own 1000 BTC? CONGRATS! You are among the TOP 0.00002%, or among the top 1000 people.

Do you own 10,000 BTC? CONGRATS. You are among the TOP 0.0000007%, or among the top 50 people.
