If Bitcoin does go up again, as some people are saying, it's going to be even more unstable than it was before... It's not something that smart investors are going to throw money into -- or maybe they will because of the risk... Cryptocurrencies nowadays, before they get serious and stable out as a second currency that we can use alongside our own, are going to be seriously unstable and have these huge crashes. Sadly, I don't think the Bitcoin crash was the last of them, as it was only really the first. The mistakes that lead to the Bitcoin crash will happen undoubtedly to other cryptos in the future until people have a better grasp of what they are and how to use them.
