How much of the thread have you read?
Perhaps you should show a little proof of work instead of merely dishing out assignments.
That's the problem I have with some newbies of nowadays, they are just too lazy to read. They just everything to be served on their table. This is a thread that has discussed extensively about the DCA and other strategies of buying bitcoin, yet here we are, someone is still asking that I should explain how DCA works. Instead of going through the thread to read and digest more knowledge himself.
Showing a little effort can surely be helpful, and if there is grappling with the materials, then any questions and interactions would be better informed by such grappling with the materials.
