@BoltonBailey will you compare the close of Dec 31 vs same day the prior year, or vs Jan 1 same year, or Jan 1 to Jan 1? I ask because it came up in this market and has many confused.
@deagol I think what makes the most sense is to find the closest time to 11:59:59 pm on Dec 31st UTC.
@BoltonBailey The description refers to CoinMarketCap, and they have historical data with daily closing at midnight UTC:
So this year's Dec 31 would compare against $93,429.20
