There investors that may not want to go in all at once, they may decide to keep some percentage of there discretionary income and them use the remaining percentage for buying the dip. As per being a low coiner ,it also depends on ones cash flow for someone with a good cash flow management that may have a good amount of discretionary income after sorting out all there expenses may decide not to put all there discretion into buying bitcoin at once they can decide to use some percentage to DCA and the remaining percentage for buying the dips.
Going all in at once is not a bad approach or method if the funds you are using to go all in is from your discretionary income because our discretionary income is meant for Bitcoin accumulation but it will be very disastrous and wrong to go all in using money meant for other expenses that is using money outside your discretionary income. and doing this can be seen as a gamble because it implies that you are using the money outside your discretionary income to buy Bitcoin and then hoping or planning to sell soon if there is little increase in the market and this is why some persons panic and sell at loss because when they have this intention and it doesn't go as planned they will panic and sell.
Well if we talk about long term holding actually I don't see anything wrong about deciding to use all their discretionary income to buy Bitcoin.
Since somehow this is good move especially if they don't have any plans to diversify or explore on other investment since buying lots of volume would give them a chance to earn more returns on Bitcoin.
What I really think will be wrong for doing that is if they put all in on their Bitcoin short term trades since there's really a good chance that they suffer some volatility issues that might cause them to lose their money especially if they get panic easily.
I think in an ideal situation it really don’t make so much sense if we invest all our discretionary income, I really don’t think that is a very realistic idea, because we can only invest some of our discretionary income into bitcoin, there are guys who do such things like investing in bitcoin with all their discretionary income, that would be a very wrong move.
However if we have a long term plans in Bitcoin investment, we can always try to stay consistent and buying bitcoin on a regular basis with some amount of our discretionary income, but I must still say it again, we’re not meant to invest all our discretionary income into bitcoin, investing some part of our discretionary income would be more sustainable.
I know there are folks who still invest all their discretionary income into bitcoin, and it probably would work out for them because they have some efficient plans and ways of buying and accumulating bitcoin, that they have different cashflow and they feel it’s sustainable to them to go that much aggressive and also having the mindset of being careful with their level of aggressiveness.
