Do you think there is room for another currency to provide the use case for daily transactions; or will bitcoin eventually succeed at this? If you think bitcoin will succeed, how long do you think it will take?
It seems to me that you are looking for a perfectly stable cryptocurrency and that does not exist, even the dollar is not completely stable and it moves when compared to other currencies and the worst part of all it moves negatively against all commodities and services, at least the volatility that bitcoin experiments is a net positive for the market and since most of that volatility is created by incoming money once the market is mature enough and the incoming money is a tiny fraction of the money already present then we could begin to see bitcoin flourishing as a currency.
