No doubt the DCA strategy is a good strategy when it comes to bitcoin investment. You can buy bitcoin with the DCA strategy anytime without waiting for an entry point, but it won't guarantee you will hold your bitcoin investment for the long term. If you want to succeed in bitcoin investment and hold it for the long term, you need a steady income that will always cover your daily expenses and give you a discretionary income you will use to invest in bitcoin consistently and build up your bitcoin investment. If you have these two things and you discipline yourself to always accumulate bitcoin with your discretionary income, you will have no problem holding your bitcoin investment for the long term.
