I remember in December 2018 bitcoin reached to the bottom around $3200 so I guess the market was already reached to the bottom. Hopefully in the next year we can see the better market.
Just think about the improvement of the bottom price of bitcoin. in 2018 the bottom should be around 4k but this year the bottom price was around 7k and next year it may be take 10k or above as the next bottom. Usually the bottom price must be the double price from the previous bottom price.
Bitcoin made progress this year, from bottom to where it's now. Some alt-coins made progress too, but not all of them, some are
having their bottom right now. I would like to believe that this is the bottom, I'm buying some alt-coins when ever I can.
Next year will be crucial for many coins, Bitcoin halving is coming, many things are happening, competition is hard and developers will
need to give their best for their coins to be noticed.
