At first I want to say: Read my post carefully and don't spam.
We all wanted high price, higher than 1000$ and got it, we got even 19k and there people were hoping more than 20K, they think like it's infinitive.
Did so high price do a good job? No, higher satoshi/byte fees became even higher in value because of price rise, some exchangers closed registration and etc. In reality there was no need of 19k but I think currently it's best to see price between 5000-8000$. There isn't so much demand.
You want high price to get much from holding? Seems you hang on bitcoin and are only selfish.
The answer is very obvious, those people who invest a huge amount of cryptocurrency in the market are expecting to earn a decent profit after then end of sale and they want the price of bitcoins to increase in order to earn more profit.
