That is the main reason why investments by public are not as active as they use to; you could always just get it at a lower price after the ico. However I think if a project delivers on a product and start generating traction that sentiment could change.
that's right ... that's what makes a lot of people stop buying tokens when ico, because they know that they can buy at a cheaper price after ico
that is also why many ico fail and cannot reach the softcap even after a long sale period
I'm in full agreement with your posts. One of the crucial reasons why a considerably number of ICO's don't meet with the hardcap is due to the volatility of the market and influence of the market.
