I am wondering if Bitcoin price will reach $20.000 this year?
Yes, trust bitcoin and be optimistic all the time. Don't let yourself be down by different negative speculations. Stick to your plans by not looking at the charts everyday, give bitcoin enough space for recovery.
Halving season will not change the price significantly,cryptocurrency always work this way;
The last halving gave nice price but it doesn't took the effect immediately.
As it was said many times, bitcoin price is unpredictable. We can only guess, and my guess is "no". Bitcoin may rise to $20k in 2019, but we would be lucky to return to $10k in 2018.
It's fine to say that it can't go back to $20,000 for this year and what you said is what makes bitcoin possible to get back to that price, it's unpredictable and loves to surprise. I hope that surprise will be positive for the next months.
