basically nobody is interested in using crypto currencies as currencies..at this pt . People are mostly interested bu the lure of quick easy money.
I know that some cryptos do stuff in crypto world...ie serve some purpose..don't really understand that stuff but get the general concept.. seems that btc has become a store of wealth simply as its gone up so much in last 20 months ish and because the currency angle didn't work..or atleast hasn't yet
