Bitcoin (BTC) has been profitable as an investment 98.2% of the days since its creation, data from holdcalc.com as of July 1 indicates.
Counting 3830 days back — to January 4, 2009, one day after the coin’s Genesis Block was hashed — holdcalc’s data suggests that on 3671 of these, it was profitable to buy bitcoin (BTC) as an investor.
That leaves 69 unprofitable days — which include virtually all days during December 2017, at the apex of bitcoin’s historic bull run to $20,000 — as well as almost all of January 2018.
The most recent cluster of unprofitable days recorded in hodlcalc’s data are during the end of last month — between 25 and 29 June 2019 — when the coin was trading between the $11,170 and $12,907 price points.
Parallel to holdcalc’s rolling statistics, a cryptocurrency market analysis published by twitter handle CL on June 24 suggests that bitcoin has entered the so-called “stealth phase” of its renewed bull run.
