I guess Bitcoin is sort of a revolution and is going to change the entire banking industry which - by and large - is pretty dysfunctional. Banks operate on old systems being around for many decades and having undergone constant upgrading. The banks know that they are in need of an uplifting and upscaling. Banks surely want the technology. But Bitcoin, they don't want because it makes the banks disappear sooner or later. That it is not wanted is unfortunate because Bitcoin is empowering people who never had access to a bank account. All they need is a phone - which almost everybody has - and a so-called wallet. No Western Union, no banks, no Visa, is needed. Transfers happen one on one without intermediary, instantly and super cheap. If that's not revolutionary. ?
By the way, the price for Bitcoin goes up because the amount (not the value) of FIAT-money like USD is constantly inflating, meaning that purchasing power of each $ is getting less and less in relation to the amount of currency. The world is suffocated by ever printing more money. But Bitcoins supply is limited. So, the value is constantly rising. It's not a bubble! ?
