Yes i do believe crypto currency can help us makes changes especially in business aspect in terms of investing with the help of technology.also it makes changes in the life of all people who take part of it.
Now you're not to think if the cryptocurrency will change the world, but if it'll survive in the nearest 6 months, especially ETH and BTC. It's a hard period, people are sick and tired of manipulations, and there're few people who would like to engage in cryptocurrencies!
