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... 
I never think about that, and everyone maybe have same opinion too. We know what you called thousands of cryptocurrencies created it is because each dev have their reason behind their project. But we can't generalize it as crypto is one big ponzi scheme.
