Do you think that in the future it'll be possible to buy food or groceries with Bitcoin? I know that volatility is a huge issue for Bitcoin to be accepted as an alternative to traditional Fiat, but merchants and businesses could quickly convert Bitcoin to a stablecoin minimizing the risk of loss. What are your thoughts? 
I guess there might be a chance for bitcoin to be used to buy food or groceries. In fact, I guess there are a few small merchants who do accept this cryptocurrency as a payment method. However, I do not think that using bitcoin is more convenient than credit cards or other Fiat cards. Since the international visa system develops, there are many rewards and cashback which are very necessary for those buying many things 
In the next few years, we has a chance to witness a spike move from traditional payment to cryptocurrency payment. But after that, people need to do a lot of thing to prove that bitcoin is suitable to join the world payment system
