The future of money is here, recent price increase is due to lack of trust and confidence in the current fiat system. A lot of buzz going around about bitcoin right now, once we crack the $10k mark... we will see interest explode from the average Joe.
Everyone says "what if I had got in during the early days?"
I say "what if its still early?"

Bitcoin certainly has the potential of becoming the main currency in the world but what hinders this development is the differences of the economy of each country in the world. Most countries that are in the "developing stage" have different priorities on improving their economy and providing internet access across seems their least priority for now. You must consider that once you change the fiat as the main currency to bitcoin (which is decentralized and virtual in nature), developing countries would experience difficulty in adapting to this change, thus leading to stagnant growth instead of actually improving.
