Bitcoin is not a currency its a steak. My corner grocer had T-bones on sale last week for $5.99 a pound, this week theyre $10.99 and next week they might be $6.99. You are never going to know the exact price of btc or steak until you check the price today. Welcome to the world of commodity trading; glad you could join us.
When I price a steak in chicken wing, then it becomes relatively stable.
Bitcoin will eventually become less volatile. The market is still very small and relatively small influxes of money can be very large compared to the market value of the coins in circulation. It's still a very young baby, don't forget that.
