Of course, just the way that our skin color is different, so is our income and discretionary income. In order for you to invest without selling your bitcoin when it's not of your will, you should use an amount from your discretionary income that wouldn't be a burden to you so that you can continue buying with DCA regularly every week consistently and persistently for 4-10 years and above. Before you know it, your portfolio will be increasing gradually overtime.
Bitcoin investment is a long-term investment for the future so there is enough time to keep on accumulating till you reach your bitcoin target, if you do it the right way and not after little profits or invest over aggressively outside your discretionary income.
Jokes on anyone that thinks they can buy during the dip, sell when they make profits then wait for another dip and buy again, such person who keeps disturbing their portfolio is not a real investor, what happened to patience? It doesn't even show discipline cause what if an emergency occur and the money the person intend to use in buying the dip could be split or entire funds used to settle the emergency situation, that's not wise which is why anyone who want to be a real investor should have a job for a start then set aside their discretionary funds to allow their investment go smoothly instead of doing otherwise and giving a trader vibes. Bitcoin investment is not as difficult as some folks think, it's even good that more people understands and put it to practice so on the long run it would influence their general way of life positively, there's no harm in being patient and discipline those are very good traits and investing in Bitcoin can help people without them possess them on the long run if they're determined and follow their investment diligently.
