I do not assume to know the mind of others but personally, I chose Cryptocurrencies because of the freedom it provides (Both financially and Technologically), I can now send funds in the form of Cryptocurrencies to anywhere in the world in just a few seconds and thanks to Cryptocurrencies, I can now afford the funds to send.
