there are a lot of us demand shop that accepting bitcoin as payment, but from this forum i found out that there are some people unwilling to spend their bitcoin, so I want to asked If you found a shop that accepted bitcoin and fiat as payment, which one will you used?
if you are using bitcoin then maybe today 1 apple is 0.0008 btc , but tomorrow with 0.0008 btc you can buy 2 apples, but if no one used bitcoin for shopping then there won't be any shop that will adopting bitcoin anymore
so what will be you choice?
Since bitcoin price reach $1200 level and cause higher fees and it takes a long time to confirmed, I can't imagine how we could use it for buy an apple in a shop which it need more than (in fiat money) normal price to buy it as you need to pay higher fee too.
Another reason such as you have mentioned, people tend to save their bitcoin as long term investment due to the price grow up over time, so I vote for fiat money too.
Well Fiat Money is convenient for all people because it is the most use and not all can surely relate with bitcoin, and I think that the first fiat money that has been use in the galleon trade back then was just shell ornaments and silver, back then there are no specific currency for some countries that are not advance and back then it only needs the physical money for the transaction of trades and people then are more familiarize with fiat back then up till now!
