Don't panic with today's conditions, I will share a few bitcoin price growth simples below:
1. 2009: $ 0,0001
2. 2010: $ 0.07
3. 2011: $ 4.5
4. 2012: $ 14
5. 2013: $ 780
6. 2014: $ 320
7. 2015: $ 410
8. 2016: $ 940
10. 2017: $ 20000
11. 2018 : BAD
12. 2019 : BAD
13. 2020 : GO TO THE MOON !
Note: follow the USD price today.
I see every year bitcoin experiences good growth, but in 2014 and 2015 bitcoin down.
2017 is the peak of bitcoin, and in my opinion, 2 years (2018 and 2019) will be a bad year for bitcoin, then in 2020 bitcoin will create bullish again. I think this is the reason some people say that 2020 will be a good year for bitcoins.
