Is forking a coin like monero or bytecoin the only way to create a privacy coin? or is there some other blockchain? like erc-20 but for privacy coins
You can get another privacy coin by forking monero and bytecoin, or any other privacy/ERC20 token as you have said. But that’s not the only way that you can get a privacy coin. That these coins are existing is a proof that another privacy coin can also be created from scratch. So, it’s not a must that you have to fork any of these coins before you can get another new privacy coin.
Moreover, I believe that there are so many other privacy coins in the market, more than you would even imagine, but the thing is that most of them are not really that popular. Even monero and other ones like Zcash, you would hardly see anyone making use of any of these privacy coins these days. So it’s not really like people are going crazy for them or something like that.
