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.
I want to believe the rise in stable coin will do this better and I believe the increase in bitcoin is as a result of successes of bitcoin. In some cases a size of dollar can defend the stable coin which enough to back the digital coin. I think this coin can cater for challenges of volatility in calculating value of purchase and engage the ease of transaction online.
