Bitcoin (BTC) and other cryptocurrencies, such as Ether (ETH), all share a common goal: to decentralize the way people bank and to open up the under-financed and under-banked world to their own financial independence.
Decentralization and accessibility are some of the key motivators in the crypto sphere. Crypto and blockchain were not made for a specific group of people, but for an inclusive group of people. Owning crypto is simply a caveat, an advantage of moving away from the centralized world, but it is not a necessity.
