What will happen if bitcoin transactions became anonymous like Monero tomorrow? Will it increase the demand of bitcoin even more in the world ? Or will it have negative effect like government making restrictions on bitcoin ?
Bitcoin is decentralized and promotes privacy and anonymity. Bitcoin transaction can be seen on the blockchain does not mean that, you know who owns those coins and who owns those wallets which is receiving and sending transactions. Bitcoin transaction is anonymous and it is the first cryptocurrency that gave anonymity to its users. If you want to remain anonymous don't use CEX and use connect your electrum wallet to Tor when making any transactions. Also don't use one same receiving address for different transactions from various people. Proper bitcoin address management give you better privacy and keep you anonymous.
