yes it is, because many companies started accepting BTC and one example is KFC Canada.
Wow, you can buy processed chicken for BTC, how does that change anything or prove it's the currency of the future? How many people do you think will pay a fee of $10 to buy food worth $5?
Bitcoin is not suitable for use as a micro-payment due to the problem of expensive transaction fees and the confirmation time is quite long. If this mass can be resolved, then bitcoin can be a very effective payment alternative.
That's true. All we're doing here is speculating on whether it can be upgraded and fully accepted around the world. It's not that hard to make the fees lower and transactions faster. Unfortunately it requires miners to "vote" and this is a huge problem. I'm investing with a hope that we can one day reach a consensus and upgrade the network. If not my money will go down the drain.
