We may have seen many developments related to bitcoin and cryptocurrency in general but I think we are still not that near yet to being mainstreamed. Though there are other countries that legalized bitcoin, there are others who are banning it. Some countries are ahead in technology while in other countries even electricity in some places are lacking so it would be hard for it to be mainstreamed.
As we are already part of the crypto world, it seems that we are getting closer to it but if I ask people randomly if they knew about bitcoin, many don't still have an idea what it is. Step by step we may be able to reach the day cryptocurrency will become mainstream.
