Maybe they're seriously voting
Some people are truly believing that bitcoins will replace usd one day.
You should never be surprised by human stupidity
Not replace but supplement and ignorance == lost opportunities

This topic shows that some people were claiming that bubble is over while it kept deflating 2.5 times more.
But at the same time were talking about small amounts by current standards
The point here was that timing is important and understanding the market not just saying the sky is falling
If one invested 10k at that time how he has 200k USD
If one listened to the OP now he has 500k USD.
Small amounts?
By today's standards
Of course
But as we lack crystal balls we need to follow our best judgements if we knew it would be worth what it is now
A lot more people would have bought at even 7.50
