The thinking of new peoples who wants to invest in coins, they first of all want to know the benefits, security, alternatives and effect of invest in their lives. Several of peoples doesnt have enough knowledge of coins who are in already in market, some of coins are includes in this time.
Cryptocurrency and specifically Bitcoin is here to stay, for sure. However, unlike fiat money, there is a learning curve here because if one is not careful anyone can lost the keys (or even the password to any wallet just like the famous Peter Schiff) therefore we can say that there is a little technological barrier in here and an ordinary guy (just like me) has to spend some time learning the ropes. Now, if one is interested into the investment side of cryptocurrency there are risks involved and one can manage those risks well through education. Will there be a one-world cryptocurrency? No, that is already a far-fetched dream for me. In fact, we have a big problem of pushing Bitcoin to be the globally used cryptocurrency, for that matter, due to many factors.
