Do you think if BTC had a stable price which could only be altered by $0.01-0.10 it would still be as popular and as used?
No way! If you look at the past history, remember that all currencies are fixed in USD and USD in gold. It has been a very short term, but unfortunately it has been a failed attempt in the long term. It was then that the price of 1 ounce of gold was fixed at 35 USD. If you check the current price momentarily, you will understand what I mean.
