What do you think is the best way to measure the popularity of Bitcoin? Some say that amount of transactions or used addresses are good measurements but in my opinion those are not really good.
Yeah. Those are not really a good indicator of the popularity of Bitcoin. It could just be the same people making transactions over and over again. Or it could be people with multiple addresses. There is really no good indicator of how popular Bitcoin is. All I can say is that it is becoming more popular as you see more and more places starting to accept Bitcoin.
