I have suggested a few small changes. Sorry if I am being picky, but I assume that is what you are after. I am not very happy with the "in a similar fashion to" part. It doesn't sound right, but then I can't think of an improvement either.
Bitcoin is the first decentralized monetary system, which is hosted on the web by regular people.
Bitcoin removes the need to use third parties, like banks or credit card companies, in monetary transactions. That means not only cheaper and faster payments, but also more financial freedom as governments or banks can’t freeze the funds of citizens for political or other reasons.
The amount number of bitcoins has been limited from the beginning so that there can never be more than 21 million bitcoins
Bitcoin has indeed been possibly the greatest best investment of the year because it’s value has gone up thousands of percents
Thus it encourages cutting unnecessary consumption and saving money, instead of taking large amounts of debt, because in deflation the value of saved money is growing unlike in inflation.
How about: Deflation constantly increases the value of money, thus discouraging unnecessary consumption and the taking on of debt, whilst encouraging saving.
Although it’s worth mentioning that mining has become more and more computationally intensive because of the huge growth in miners and improvements in their hardware.
I would remove "although" at the start unless you have a contra point to end the sentence.
Many people believe that bitcoin is about to disrupt the monetary system in a similar fashion that to how email changed the way we can communicate. It’s a technological masterpiece and a demonstration of how smart technology can solve even problems that once looked appeared impossible to solve.
You shouldn’t simply believe this video though, because that wouldn’t be smart. Read more about bitcoin in Wikipedia and other sources and study the system carefully yourself. Many people that have started out skeptical have been surprised on by how brilliant the bitcoin system is.
Bitcoin is more than just a superb way of transferring money and storing value
