Even considering Bitcoin and cryptocurrency become more popular in last 3 years, i have doubt they'll make comeback even if unless they don't improve UI/UX of their software. I remember merchant have to keep their computer/server online all the time (to make their goods searchable by user) and user need to install software which is a bit resource demanding where search took some time.
Agreed, also part of the reason of low activity in Openbazaar might be because much of the holders did not buy bitcoin to spend, they bought it to hold as an investment. There might be some of them who might try it to buy something occassionaly, however, they might also not use it as their first choice of currency for shopping much of the time.
