I'm not with the bitcoin community sincel ong time but .. Both SegWit and Lightning network should come in the future, developing Bitcoin more and more will bring people and cause a price increase .
If people lost their funds in Mt.gox then It's because they stored their coins in an online exchange, people probably didn't have much knowledge back then but what is their excuse in the recent hacks like in Bitfinex ? there isn't any , same thing for ponzi schemes (HashOcean where few millions were stolen as well) , All those things affect the price.
We don't need price increase with maniuplation and stuff , we want something that increase with stability.
