I think price of bitcoin increased from 6th April much more then just 27%. Closer to 40%. Let me check. $6600 to $9300. Yes, $2700 is almost 41% price increase. Sort of huge if we would not talk about Bitcoin.
In comparison to commodity markets a rise of 40% might occur in turn around at market bottom. The shares associated with a market can move this much because they are leveraged to profit margins of the base product.
In Bitcoin however, the supply increase normally apparently in commodity price rises does not occur. As we know the Bitcoin production is a fixed and self regulating system, this results in the price changes being quite rapid and speculation by the market quite a large part of supply and demand.
