I personally didnt lose hope in bitcoin, cmon last year this time bitcoin was 1000 dollars now it wont go under 5800$ so people have confidence in it and buy it for 5800$... I guess the price will go furhter up especially when 2020 the next halving is... however we need adjustments on the usage because I would really love to spend my bitcoins on local shops and buy things with it as this will drive the price further up as the demand will increase with every shop accepting bitcoin as there can not be a bigger supply than 75 BTC per hour....
