There is no gainsaying that cryptocurrency is one of the strongest investment platform in the digital world.
Despite all the agitations, media attacks, government attacks and attacks from groups and individuals, yet it is still going.
If cryptocurrency will end, it ought to have ended long before now and would not have survive to see year 2019.
One of the strongest points of cryptocurrency, apart from the technology, is the community.
Instead of the community reducing, it is increasing, because more people are becoming aware of cryptocurrency allover the world. Even if some seem to have taken a break, more people are being added.
I agree with you that cryptocurrency brought a new direction to the world of finance that quickly gained popularity among people.
However, due to the very high volatility of cryptocurrencies, they are used mainly as a tool for speculative trading, and not as a substitute for paper money.
