I don't know why someone would think that they can't get more bitcoins. You can buy them off an exchange whenever you want.
Because they believe bitcoin price will go beyond their
purchasing power in future.Even at current price, many people can't afford to buy a whole bitcoin
Then people need to be educated. It doesn't matter if you can buy a whole bitcoin or not. If you want to buy $10 worth of bitcoins, you can buy $10 worth of bitcoins.
people are to stubborn thinking in fiat terms, you don't need more coin, you need more value per coin, stop comparing it to fiat trash where they keep printing endless because the value keep dropping
bitcoin work as opposite of this, you need an increase in demand(this is the primarily problem) that will exponentially increase the value of each coin, so you need less and not more
That's what I meant to say.Everyone believe that value of their coin will exponentially increase in future so they want to save it till that happens.
Just being an exponential increase is not a sufficient reason to horde. An exponential increase of 1% per year over 50 years is only 64% (compared to 50%).
Fears of widespread hording due to deflation are overblown. The average depreciation rate of the U.S. dollar over the last 100 years has been 3.22% (exponential, by the way), and we don't see widespread dumping of dollars. So, if Bitcoin's appreciation rate is 3.22%, we shouldn't expect widespread hording of bitcoins.
