At this current market scenario, holding bitcoins gives better ROI (not a financial opinion but it is market trend). Bitcoin as a security, no, because, at the moment, many governments are hostile.
So the question has come, will Bitcoin be adopted by mass? The answer is, It will take time, but mass adoption will faster than Credit card. Just check the history of Credit card. As you know current model of credit card was issued by The Charga-Plate, developed in 1928, was an early predecessor of the credit card in the USA from the 1930s to the late 1950s. But mass adoption started from late 1970s, after accepted by major banks.
That sounds very promising because now many banks, insurance companies and other financial institutes are integrating blockchain in their structure.
As for me, it`s very interesting - what will be with BTC price after border of 10k$. It`s very important psychological mark.
