Satoshi said that:
The price of any commodity tends to gravitate toward the production cost. If the price is below cost, then production slows down. If the price is above cost, profit can be made by generating and selling more. At the same time, the increased production would increase the difficulty, pushing the cost of generating towards the price.
He knows that the price will be volatile at the beggining.
This fine detail from Satoshi hits different, knowing too well that is what's actual happening atm!!
Btw at the moment markets aren't as active because many bought at a premium price and forced to hodl as price is in red on their books not until price climbs back up for them to break even or go for the profits..and this will only happen with new players to buy the cheap coins.
