For anyone who considers the bull run of 2017 and subsuquent crash of early 2018 to be out of the ordinary, that’s because Bitcoin isn’t ordinary. Nothing like this has every existed before. As a method of value transfer first and foremost, with adoption growing, there is no limit to how high the value of Bitcoin may go. Fiat money is inflationary with a hard floor value of 0 that it is slowly but surely trending towards, and designed to do so. Bitcoin on the other hand, is deflationary by design and has no hard ceiling value, it can and will continue to grow in value infinitely.
