There isn't such a thing as an 'ultimate value' when it comes to Bitcoin. In most cases the only thing people more or less can be sure of, is that the price will continue to go up throughout the years. If we had to believe experts back in the days, Bitcoin wouldn't be able to surpass $100 in 2013, which it did. Bitcoin wouldn't be able to surpass $1000, which it did in the same year. After the MtGox drama Bitcoin was said to never be able to recover again, which it did. This stupid form of underestimating Bitcoin has made these idiotic experts change their view on Bitcoin quite a bit lately. Instead of them saying it won't go through this or that level, they say Bitcoin might reach $50,000 or even $100,000, but it will crash for sure after that. They don't understand how they only make themselves look like a bigger fool than ever before with this hype riding behavior.
