Yes volatility and price fluctuation is what I see as the hindrances to bitcoin adoption as a Leger tender or payment option for most reputable or small businesses. And I don't think this can be removed from crypto. Volatility is what we need, price fluctuation is what we need also....so how do we wonna deal with this?
Apart from this volatility is which is really an issue with most businesses accepting Bitcoin, I truly believe that the most problem is the Government's stand on Bitcoin. How can Business owners accept Bitcoin for services/goods if the Government of the country they operate in is against Bitcoins adoption? that could be a crime, right? So I think this is the biggest problem with Bitcoins adoption by Businesses.
And if the economic crisis that we are experimenting gets any worse it is entirely possible the posture of the governments against bitcoin will get even harsher, now if this is the case then some may argue about whether or not bitcoin will ever be adopted massively by the people, however if the economic crisis gets any worse then people will begin to look for alternatives to fiat currencies and will begin to use bitcoin even if the posture of their local government is very negative against bitcoin, so while that is an obstacle now it is likely that in the right circumstances people will not care at all about this.
