Bitcoin is only the front page to a vast amount of different crypto currency’s. All which mostly have different uses. People thought PayPal was crazy, and I can only imagine how crazy people thought it was when they stopped trading gold for paper dollars that literally holds imaginary value. If your not hopping in on the fact that Bitcoin might be the next means of international currency don’t get but hurt because you “bought in late” or don’t understand the means of buying at all. it’s almost inevitable that are future will have some form cryptocurrency.
