Total crypto market capitalisation, according to CoinMarketCap, was up 2% for the week, to $817bn.

Bitcoin has updated two-year lows below $15,500 in the past week on news of the possible bankruptcy of cryptocurrency lending service Genesis Global Capital.
Bitcoin is under pressure from institutionalists whose risk appetite is firmly tied to stock markets. Bitcoin continues to look for a bottom from which it can push back, but the negative external backdrop is not yet conducive to buying.
