the price of ATH Bitcoin was $ 20,089 on December 17, 2017 and this year's chance for Bitcoin price to rise higher than ATH price is likely to happen, because this year I saw crypto market was very good and market cap also increased higher than last year, so this makes me believe if people start to investing in cryptocurrency again and this will have a positive impact on the price of Bitcoin, because the dominance of Bitcoin in market cap is more than 60%, so if this year the market cap continues to increase then I believe Bitcoin price will definitely increases very high and beat its ATH price.
