Sometimes many people fail to invest in bitcoin not necessarily that they don't have money to invest. Or that they need extra income to income to boost their investment chances. Some of these people are just looking for someone to act as a motivating factor for them before they can invest. Many people in here develop more interest in investing and hodling bitcoin because of their continuous visiting and reading of this thread, and seeing the knowledge that are being shared here and it motivated them. There could be several reasons why many hesitate to invest, but like you said above, investment is basically a choice
yeah investing is a choice you can't actually force anyone to invest but you could try convincing them by showing them the beauty of investing in bitcoin. But there are some people no matter how you try to motivate them they won't still give a shit, they would keep on procastinating. Someone having the financial capability to invest in bitcoin and still didn't, no matter all the impacting about are great and profitable investing in bitcoin is. I would say "is the individual loss" because even though he or she decides not to invest in bitcoin it's still won't stop bitcoin from growing massively. So those who are opportune to know more about bitcoin should grab that opportunity and invest even if it's individual personal choice to invest but still investing in such wonderful project (BTC) is a right choice.
Trading and DCA has nothing in common DCA is a process used in accumulating bitcoin and most of the people who use DCA process are those who want to buy and hold for long time so I don’t see anything wrong with saying DCA has something to do with bitcoin holding. But for bitcoin trading you don’t need to follow DCA at all you just need to use the money you have at hand enter the market and start their trading losing or winning, so i don’t see any relation between DCAing and trading that’s a wrong connection if you ask me.
I also think like that because logically, people who are trying to collect Bitcoin and hold it for a long time don't immediately think about selling in the near future, so it is very feasible to use the DCA method in that case. Meanwhile, trading is a very different job from collecting because the people who trade in the market are people who are targeting profits in a short time or quick profits in a certain amount so it cannot be compared to people who are collecting Bitcoin by run the DCA method.
you know trading not just for short term profit is also for short term losses because we all know that In trading losses are inegligible, though alot of pro do earn good profit from it sometimes but still can't ignore the great risk attached to it. That is never advisable for those expecially newbies with half-size knowledge about trading to not engage in it, instead they should take their time to lear more or engage in long-term investment which is way better. Nothing like accumulating more bitcoin in your portfolio using all the cool method like DCAing. And seeing your portfolio grow massively though you may experience some decrease or increase in price due to volatility but most time it always end up with a massive greens. Due to your long-term investment it would be more profitable.
