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.
Well because of course we will be required to use Crypto for now because digital money will definitely be used as a substitute for paper money someday because it is a real condition and now usd coins already exist in various markets making it easier for us to save assets that are safe because price stability from usd so if later there is a change in our currency ready in its financial form and Crypto is not an investment but returns to its original function as a digital currency.
