Wheres America has just gone to bed, i dont understand Asian languages and Europeans haven't finished breakfast, i am happy to bring you the news from 
The reason for the incredible rise in Ram prices seems to have been this:
Due to an unintentional configuration of the Bancor Relay weights on the EOS blockchain, this parameter is set at .05% rather than 50%. This introduces some heavy slippage for buying and selling large quantities and causes more volatility than desired.
Oh i am just confronted with my vaning financial knowledge, but to my understanding, the current algorithm, seems to pick up price afrom a volatility of 0.05% whereas it can be set much higher, and changes in price don't lead to further increases.
