jerry0, you thought wrong as well as many others, and and now you are disappointed with the development of events. But it's not all so black, and all that has happened you should use in the future and start thinking differently. There is no chance that price is go up to 100k $ or 1$ million back in 2017, it was only matter of time when the correction will take place. Media is pumping this story so high that it seemed that the price would never stop growing.
You just need to look into their past, and even BTC have only 10 years of history, you would see some things repeat in cycles. Some may not agree, but situation is similar to 2015, price was just around 200-250$, and it was not easy for users to accept it after the price has passed 1000$ mark. Now people are disappointed with 3500$ while they are thinking about 20 000$.
Perhaps there is no progress as regards price, but there is progress in development and adaptation of BTC. Lightning Network is progresses every day more and more, and this is something that can greatly contribute to the adaptation of BTC as a digital currency.
You're looking at a very narrow picture, try to look at things in a broader context then just price.
