From the charts I'm looking at (market watch), it appears that other cryptos have lost more than bitcoin, by percentage. Am I incorrect?
Coinbase's weekly losses chart[0] captures some of what i hoped to express in my parent comment. Bitcoin is interesting because in a way, it hasn't so much lost value lately as not risen with the market the last couple of weeks.
