My possibly naive takeaway from this is that on the retail adoption side this is a necessary evil. upon acceptance a company may initially sell straight away into the market be ause they are basically testing the waters, but as their btc sales stabilise they will (lseeing the successful example of overstock) begin to hold a percentage in btc. this will equal less supply and will encourage b2b usage in the medium term even though it has a price dampening impact initially.
its part of the reason for the stagnating price but will also be part of the reason that it eventually takes off again.
id guess its a 12 month lag between accepting, holding and then paying suppliers in btc.
