I already asked some questions in this thread. In order not to flood here, I decided to add three questions in one thread. I apologise if the questions don't meet standard.
Question one- Volatility question:I understand that bitcoin volatility is caused by demand and supply. Then, there is fixed 21million supply, if the 21million bitcoin is mined, will it make bitcoin price to be stable? Because there will be no more demand, there will be no more supply. The bitcoin in circulation will keep circulating.
Question two- PoW question:Bitcoin and Ethereum uses the PoW consensus. Why does ethereum now process transactions faster than bitcoin. This is without consideration of sig wit or beacon chain.
Question three- blind signature question:A blind signature, is a form of digital signature in which the content of a message is disguised (blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature.
Alice is a vendor that made her address publicly alongside her real name. Bob buys something and pays Alice through bitcoin. Bob will be able to link Alice address to her real identity.
Since blind signature says a resulting blind signature can be publicly verified against the original(unblinded message). Why does bitcoin not make Alice address disguised(blinded) to Bob and yet it can be verified by miners or checked on explorer. By this Alice can be completly anonymous. Is it not compatible or it is not making sense?
