When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed. However, a change in average kinetic energy is not directly proportional to a change in average speed. 1.
An appreciation means an increase in the value of a currency. It means a currency is worth more in terms of foreign currency.
Bitcoin is not a currency in any meaningful sense of the word. Is Bitcoin a store of value? Gold apologists love to describe the precious metal as a store of value.
