The basic underlying idea behind the use and creation of cryptocurrency is to present financial freedom to everybody no matter where you find yourself in this world. But the volatile nature of these digital currencies got me thinking, what if the whole idea of blockchain and cryptocurrency is just one giant Ponzi Scheme? Within a short period of time, there have been about thousands of cryptocurrencies created. Majority of these digital currencies are either trying to solve problems of a particular cryptocurrency by presenting solutions they think can help improve financial freedom. This usually gets me wondering and thinking. If you don't agree with me on this, please share your thoughts... 
Bitcoin has been called as ponzi scheme in countless times since it was created, but i think there is no ponzi can survive for long time like bitcoin.
If crypto was a ponzi scheme, it would be dead already because no one would like to using it anymore.
Cryptocurrency has a real function in our world, as a digital currency.
