People use bitcoin because of a lot of reasons, the security of bitcoin is a very good reason.Also the anonymousity of bitcoin, pay with bitcoin since it doesn't register to any name or any personal information.
Yes that is the best reason which attract customers to use bitcoin suppose if a person want to buy some credits on a gambling site and he do not want to show his identity then he choose to use bitcoin.
I think for ordinary people anonymity will not provide the functionality or any benefit to them, if you give this explanation on the target ordinary people of course you will not get additional users
even though bitcoin is not really having anonymous feature like what you're talking about,maybe some people here even saying that bitcoin is the most transparent currency ever,just see your transaction history,it will be never deleted until bitcoin doomed
Yes, people bitcoin provided anonymity for people who wish NOT to reveal their identity at the time of making payment. For normal people or customer who doesn't mind about revealing their identity, They can use bitcoin as a form of investment. They can keep it in their wallet and benefit from the increasing value in the years to come.
