Bitcoin's popularity has been increasing ever since the bull market of 2017 took place. Even with the pandemic, prices have recovered to their original levels (near $10k) in just a matter of months. More people are accepting Bitcoin worldwide, albeit at a slow and steady pace. I've seen many sites out there in the online world which accepts Bitcoin for goods and services. But the number of businesses and merchants accepting it for food or groceries are quite limited. In the physical world, supermarkets and even fast foods haven't even adopted Bitcoin yet. Fiat is still the predominant type of currency in the mainstream world, for buying items that are required for one's survival.
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 don't think it will be feasible.
Even though we have seen people buying coffee and other small stuff with Bitcoins , one should realize that , no matter what you will have to give fee to the miners , even lightning network is not completely free , at the same time I don't think people will continue to use lightning network after possibility of attack by hackers and other people.
Therefore I do think before this to continue we need to have two things :
1. Improve the lightning network
2. Invent some alternative to lightning network
Then only we will be able to see Bitcoins being used for day to day activities.
