The currencies nowadays are also fluctuating and nobody says a word, like when I think about British pound that being 1 GBP-1,34 Euro, now it is only 1,12, after Brexit nobody know what happens. The future is in cryptocurrency, Bitcoin will be there and not disappear of course fluctuates. But who cares... I think our generation need to think about the future and build it ourselves with cryptocurrency. But who knows may be in 5 or 10 years there will be something else and will change the opinions completely :)
