If bitcoin had a stable price it would be popular. Even if the price is stable or not the popularity of this bitcoin is not too much popular. Because many people dont know what is bitcoin. Many people dont need to use it. Many people dont have care about bitcoin. However it is not too much popular right now in the future i think this is the most popular coin even if the coin is not stable price.
Yup correct, the population around the world is 7 billion and 100 million are used only of bitcoin. Most of people used cash for their payment an for other things that want to buy.
And for the user of bitcoin I think it will also become popular, it is not used for investing, trading and etc. but for other online transaction or online shopping who accept it.
It will still popular because it is global currency and with this you can earn money but I think trading and investing destroy.
100 million where? We're far from that based on the userbase this forum has and all the other bitcoin related forum have. Maybe 100 million wallets/address has been reached by now but that's just because people can create thousands of wallets all at once.
Trading and investing wouldn't destroy bitcoins. First, people are buying bitcoin because they want to invest in it for the long run. Another, trading is one of the best ways to make money so definitely people are going to do it. And it seems that trading has become so common that people invest in cryptocurrencies because of it.
Trading is very profitable in crypto because most of the coins are going uptrend, this will benefit the long term holders as they will not be hugely affected with the price volatility. Bitcoin has increase so much this year and still growing, we can see more in the future if number of real adopters will increase.
