You hit the nail on the head, there is no need to complicate things, buy your own Bitcoin, no need for second or third party involvement, DCA if you want to accumulate for the long term. The main idea about Bitcoin is decentralization and that self custody, only you can have the control over the Bitcoin that you own, not necessary to belong to any community owned Bitcoin treasure. Besides, this is an anonymous forum and it is not the best place to have a community Bitcoin treasury.
