Crypto currencies and their future

I run this topic because I see that new users crypto currency are looking at only the price, and I am when I entered the world of the crypto currency from the beginning I only watched the price and looked at the short-term crisis of the crypto currency, however when I started deeper into the possibility of crypto currency I realized that the price is just a superficial part of everything, most crypto currencies have deep solutions for many problems, of course the crypto currency gives us cheap transactions and a decentralized payment system, some offer transparency and some offer privacy, essentially a crypto currency that have the purpose of existence have a bright future, in my opinion, the crypto currency is a new revolution for the world economy and much better than the current world currency, even as I think the crises of the currencies will raise the importance of many businesses that have come to collapse in small markets, the crypto currency they could also make more profitable renewable energy sources, so we are just beginning to develop a new one technology.
