If the price goes back down again to around $4000-6000, people will be able to buy whole bitcoin, I know people can buy fraction of bitcoin, but buying whole is a better deal.
nope price won't return to 4k to 6k $ or time won't return to the year bitcoin price is low. if you can't afford bitcoin then work hard and earn money then buy. if you really can't afford buying it despite working hard then just buy what you can afford. you can buy portion by portion until you can have a whole bitcoin.
