@Jay you have really impacted a lot of knowledge on me which has been helping me on my Bitcoin journey I could remember when I came here with a less knowledge about strategies of accumulation using DCA, with this tread I was able understand and add the knowledge I have gathered from here to my existing ones which has been very helpful.
Referring back to your comments, of course is very unwise to uses the money that's meant for other expenses to invest because he is likely going to get into trouble later on because when the need will arise he will be left with no option but to sell off the investment. Perhaps this could be referred as an ignorant investor whom sees a possibility of getting into trouble if taking a certain decision but still went ahead.
The idea of the DCA is very vital to every bitcoin traders as they can easily have full access to their money. Like for instance if an investor makes $2000 then he now invest like like $1200 to purchase bitcoin at the end of day he's still gonna have some amount of money left with him to sort out other needs that he might require so that it will not affect the amount they invested to purchase bitcoins
