If price went down X5 back in 2013, difficulty of mining didn't go down, now not just Bitcoin and mining, all the coins and tokens are moving down.
For somebody like me this is hell, I bought at $20,000 hoping to sell higher, price has been dropping ever since.
Let me show you some thing on price.
In 2/2/2014 Bitcoin price: $836
2/2/2015: $220
2/2/2016: $380
2/2/2017: $1000
2/2/2018: $8900
2/2/2019: $3000?
2/2/2020: $5000?
2/2/2021: $50,000?
You miss very important aspect for the price. Yes the bitcoin price kept falling and rising over and over again. But I don't believe bitcoin will hit 50k in 2020. Don't forget worlwide economy trend. During these years worldwide economy has boosted. But it is expected to have a crisis in 2020. Therefore once world economy starts to fall, people won't have a lot of buying power and very little money will flow into cryptos - Therefore no demand no price increase. I see worst cryptos times in 2020
