I guess we have to ask the question why we shouldn't believ in cryptocurrency? The vast majority of people believe that it's a bubble like there was a dotcom crisis in the beginning of 21st century. However, I guess cryptocurrency is much harder and it has millions of algorythms. I believe in crypto abd think that it cna reach heights within couple of years, because everything points at it. Of course, everybody decides by himself why he/she believes in cryptocurrency, I do it just because I have read plenty of information about cryptos and how do they work. So, there are no reason not to believe in it.
