Given that Bitcoin is considered a store of value, can you use a cryptocurrency that can guarantee day-to-day usability? How to go to bakeries, fill up the car, travel, etc? Do you know any coins like this?
When it comes to daily usability, the best coin we have is bitcoin. This is because bitcoin has the highest acceptance rate in the world, the second could be ethereum and probably a few others. Every other altcoin are held for investment purposes and not for their usability. The world is yet to accept cryptocurrency and this could be tied to the fact that the market is volatile in nature.
Bitcoin has been really functional. It's being used to purchase different stuff and even being used to pay for services. There are just limits since not all business types accept cryptocurrency. In our country, we're able to pay our bills using Bitcoin which is really convenient. I'm sure that there will come a time that even huge businesses would mind accepting cryptocurrencies.
