Crypto currency. A payment option? A ponzi? Or the future?

Hello guys
It's your potential blogger here again.
Lately, there has been a serious campaign against all crypto currencies online. Most people continue to think it is a large scale ponzi scheme that will crash in the faces of all those who refuse to withdraw from it. So the question I ask is why are skeptics so concerned with what we do with cryptocurrency?.
Before I go any further I think it is important to first define what a ponzi scheme is. A ponzi scheme is a money making platform that pays it's investors by using the money of other investors. It depends on the continued participation of people to be able to sustain itself; thus the name pyramid scheme. On the other hand, crypto currency is simply a digital medium of exchange that is independent of any central bank. It is important at this stage to point out that unlike ponzi schemes, crypto currencies use a cryptograpic algorithm to control the creation of more units. Simply put, it uses algorithms to print more cash and this has proven to be more effective than even the printing of physical cash. I like to see crypto currencies as payment options yet to be accepted by governments and skeptics.
With this said, I would like to look into the reason so many people are skeptical about crypto currencies.

*The fear of change. Crypto currencies have the potential to revolutionise the financial sector as we know it. It has the potential to whip away the physical and centralized payment options thus it is seriously been criticized by people who are benefiting from the current status quo.

*It has the tendency to wipe away social and economic class variations by making it easier for everyone to assess wealth and this isn't favourable to the top dogs.

*it is decentralized; thus nobody has control over it and this ensures absolute fairness so every investor has equal opportunity.

I could go on and on but to conclude, crypto currencies aren't ponzi schemes as the difference between them is clear. Instead crypto currency can change things for the better for everyone if we accept it and stop been pawns in the government's game of control.
