When you come to understand all of this it is easy to get why so many people prefer to keep complaining than to do something about it, complaining is many times easier than it is to try to increase the amount of bitcoin we are holding.
I agree, that's the most ridiculous reason one would not buy.
I'd like to think that those people really trust bitcoin and would like to have a large amount but can't due to financial reasons and are hoping it crashes hard so they can buy more than they can afford now.
This is why I agree with those that recommend to buy bitcoin whenever you have some fiat in hand, because even if you were to buy bitcoin at an expensive price if you hold long enough your profits are almost assured.
