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.
You are very right. The capital is the first step in gaining a huge amount of profit. But, I think its price will not drop again since the pumping has already began. My period of prediction for this event that bitcoin will be less than 5000 USD is in every January.
