Hopes are high with bitcoin but as the time goes by it always decreases without any reasons, maybe manipulation?
Hopes.... That's the real problem of people here. Instead of hoping for the price to go up while we're clearly not ready for an increase, people need to actually use Bitcoin. If you're here solely for speculation purposes, you'll get bored during a longer term downtrend and you'll lose confidence, which is your fault entirely. I'm neutral all the time when it comes to the market sentiment, because I'm actually using Bitcoin as money. Bull or bear markets don't change anything in that regard.
Who knows, but as we can see and if this could happen continuously even after the ETF decision, maybe we could see 10$ btc on 2020.
$10 BTC? Are you nuts? You won't ever see that price again unless crypto in its entirety has become completely obsolete.
