Some numbers to put into perspective...There are 21 million total Bitcoins that will ever be created and/or mined and currently 749,128 users on BitcoinTalk.
If Bitcoins were split equally amongst the population on BitcoinTalk we would receive 28 BTC each.
Taking this a step further... Considering this is a global forum and that globally there are 7.4 billion people, approximately 0.0001% of the world is on BitcoinTalk. Basically, this means one person on the street out of 10,000 is on BitcoinTalk.org.
Essentially, there is still massive potential for the growth of Bitcoin considering it is a strong investment vehicle and an asset for wealth. Every single person and their kin would be able to enjoy and nurture the value of Bitcoin for generations to come.
Keep buying and hodling folks. The growth hasn't even hit its climax yet.
P.S. I wonder how many of the current 749,128 users have more than 28 BTC each....
