now only the price is little high , i think the value of the coin in future days may reach so high so that it would become so expensive to buy it
because now the people in the world started learning about bitcoin may it become popular
If it happen in the future that the price of 1 bitcoin is too expensive for average investors then, the market will open a fraction of bitcoin which is a satoshi which I think can be affordable to us. The market will also adapt with the trend of this technology. Anyway let's just be practical as everything will follow with the flow.
You sounded like the fraction is not in use already. We have 100 million satoshis that makes up a single bitcoin and that on its own is enough of a fraction to take advantage of.
Even as it is now, the current price is still very expensive for a lot of people, but they still buy the little fraction they can buy anyway, and I believe nothing is going to change when the time comes when the price is far more than it is, unless of course you want to say the price of bitcoin ends up being more than $100million, and in that case, I really want to imagine what the market cap would be like, and to me, that sounds unreasonable to see that happen.
