Conclusion: don't use bitcoin for everyday stuffs and use it very carefully in investments which can grow the amount of those in your wallet. Bitcoin is precious. There are justified hopes that its value will greater in the times to come.
Wouldn't it make sense that people who want to promote bitcoin use bitcoins for everyday stuff whenever possible? What will make it grow in value is more people using it. The more retailers that accept bitcoin because more people are willing to use it as a method of payment will grow. So if there was something that I wanted for $500, I would first find out if someone was selling it for bitcoin and buy it with that, or if I wanted to go out to eat somewhere, a place that accepts bitcoin will be a considering factor. As more retailers accept them so will others because their competitors will have an advantage. Since retailers have many benefits from using them, they could also offer a discount which would encourage more consumer use. This seems like one way we can help make it a more commonly used currency and grow it's value. People who just have some in cold storage or use them sparingly could help facilitate its acceptance by using them whenever they can.
Of course, everytime I used bitcoin for everyday stuff, I would immediately replenish that amount in bitcoins from cash.Only the last your sentence make me to not begin another argumentation about the point of view of you an me. I forget to add this your phrase to my post. So, my post would be fully meaning if I would wrote at the end: Or if you want to use it find the way to buy at least the same amount to replace it immediately.
Your consideration are more than right. It must be so because the use of bitcoin help in its spread and this spread make more possible the achieve of our hopes. Anyway if after the use of it, everyone don't buy at least the same used amount, my previous post (even can be considered as very selfish) it is the best answer that can be given about the use or not of bitcoin.
I repeat: Something rare cannot be used for everyday stuff. Cannot be used at all every day. It is like you sell every day diamonds or perls or gold to buy bread. Make no sense.
