Many Bank only allow +18 users to use money services is right for you?
so if this right bitcoin not need ID so under 18 years can use it
In our country, below 18 years of age can open account in a bank with their parents consent in which is necessary to prevent money laundering activities. In Bitcoin anyone can join the investment and transactions as long as they know how its works and the ID's will just required only if they will affiliate to their local exchanges for their future transactions of Bitcoin to Fiat conversion in which the ID was required as per government policy and below 18 is strictly prohibited to join.
ID is very important for the transparency of your transactions on the bitcoin exchange online and local activities was closely monitored and can be traced. Same here in my country I was also asked for those credentials, and as an abiding citizen I used to follow what's legal. That's the good ways to implement the regulations in each country so the crimes related to financial abuse like the example mentioned same as money laundering, and other criminal acts related to bitcoin. In this case everyone should be able to bare in mind that no one is above the law, and is subjected to conviction if found guilty against the violations committed.
