Many of us are hoarding more Bitcoins over time. That is also the reason why Bitcoin dropped sharply on exchanges
transactions in the past few years.
Will we sell out of Bitcoin one day? Like how the ring was thrown into volcanic lava.
At some point we have to cashout on our investment and be used for other things like reinvesting into other area of life or be used for other stuff so definitely we will be selling someday but that is not the focus, the focus should be getting hold on as many Bitcoin as possible and not selling when it has not reached its highest potential yet.
You do not also have to sell all your Bitcoin which is Why to avoid that happening you have to buy as many as you can today so tomorrow when you sell you are not letting go of all your Bitcoin at ones. Try to get hold of atleast 1 Bitcoin as in the future you can sell some fractions and get huge returns of investment.
