Honestly, I don't give a shit about Bitcoin pricing in dollar or whatever... I have only interest in Bitcoins itself. I already forgot about the old dollar!
I know that this (forget USD, EUR, BRL...) is impossible in a global scale today but... The really sad thing around all of this is that the mining difficulty does not drop alongside with Bitcoin dollar price...
I don't understand your point here. You talk about forgetting the dollar, but at the same time you expect bitcoin's algorithms to be based on dollar exchange rates?
In fact, the difficulty is still increasing!
I think that we need to do is:
1- Help Bitcoins being widely accepted around the globe;
2- Stabilize goods and services prices in Bitcoins only;
I'm really glad to see more people realizing that we need merchants using bitcoin and having stable bitcoin-based prices instead of dollar prices translated into bitcoin.
3- Close your bank account.
Now despite of the excellent point you made above, this recommendation unfortunately makes your post look like a joke. As long as there is no real opportunity to get food and residential property using bitcoins only, you cannot expect people to abandon these essentials. Furthermore, this would bar many ways of receiving income.
I actually think the most important thing is to have a critical mass of merchants using bitcoins to sell various goods and services. This will stabilize the currency and make it more interesting for even more merchants and consumers.
We should not forget that BTC-USD rates are no absolute measure of bitcoin value. Volatile exchange rates may indicate BTC volatility, but they may also be related to USD volatility...
