Bitcoin has fallen almost 12 percent in 24 hours as the reality of the Aug. 1 scaling deadline unsettles markets.
Current trade prices according to Coinmarketcap, which averages readings from across major exchanges, shows Bitcoin at $2,076 - its lowest price for two months.
The knock-on effects for altcoins in the top 10 were as palpable as ever, with Ethereum, Litecoin and others following Bitcoin downhill.
Ethereum has fared particularly badly over the past week, with monthly losses to its market cap now nearly $18 bln.
As always, internal reactions with cryptocurrency were mixed, some despairing while others are eyeing a keen buying opportunity.
