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.
