There's another similar project (to an extent) that is trying to achieve this (
etcetera). Regardless of that, it will be nice to have some alternatives as well (like your project).
would you guys be interested in buying/using it? and why?
It depends on how "easy" the whole process is (for buying it). If it saves me the hassle to go through an exchange (in order to buy small amounts of
BTCitcoin), just so I could send it to someone as a gift and for normal usage, then "YES".
