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
Bitcoin cannot become that expensive, someone will always be able to afford a full bitcoin, what it is going to happen is that the average person will no longer be able to afford a bitcoin, just look at the price right now it is above 6000 and how many people can afford to spend that amount of money in something that they cannot even touch? In many developing countries many people do not have that amount of money in savings so even at the current prices they cannot afford a bitcoin.
