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
Someone can buy bitcoin without having to buy 1 BTC, everyone can buy bitcoin with 0.00001 for instance, if bitcoin has a high price. There is nothing to worry about, however, if you have a view like that, you can collect as much bitcoin as you can so later if bitcoin has a high price you can become a conventional trader with people who want to buy bitcoin.
