Bitcoin is considered as a currency because it is a digital currency and you can call it asset as well because it is good for a long term investment. Most of the businessman are investing in this coins because the value is keep on increasing periodically.
I am more apt to think of it as a store of value. BTC is not able to be used for everyday transactions. For example sending $5 to a friend remains expensive and takes awhile to be confirmed by the network.
I'm interested in those who seek to overcome these issues. eBTC is a sleeping giant I think, as the project has the fundamentals to achieve mass adoption. Very exciting to think about the possibilities the future holds.
