I see the idea of building up funds first before accumulating bitcoin as a plan that will delay our bitcoin accumulation journey. Instead of trying to build up funds before accumulating bitcoin, you can use the DCA strategy to accumulate bitcoin either weekly or monthly, whenever your money is readily available. There's no pressure to invest in bitcoin; no one is forcing you to do so. The only thing that can make you sell your bitcoin when it's not time for you to sell it is when you use your whole money to invest in bitcoin. You will depend on your bitcoin investment to survive because you used all your money to invest in bitcoin.
I think building up funds first is looking for away of having a stable income. Having a stable income it can enable one to invest atleast with the amount one can afford. If we look it in the other way saving money first to start up bitcoin investment, I don't see it to be building because even if one saves some money to start up investment and no steady source of income, if their should be a problem that money is needed to solve it, it is possible that one can sell out the bitcoin to settle the problem. But when one have a source of income , even if the person is investing with a little amount in bitcoin atleast with the steady source of income the basic problems can be solved without thinking of selling bitcoin.
Saving money to start bitcoin investment is not a solution of having a successful investment but having a steady source of income can sustain an investment. Savings without steady source of income to begin investment will be a difficult experience to keep investment going .
From my own point of view, I think that anyone who is saving/piling up his funds to buy bitcoin with lump sum to start his bitcoin investment has a means of income if not he will not be able to pile up the money to a specific amount that he can use to lump sum, he might spend his savings before it gets to that amount he desires. A means of income is very important for anyone who wants to venture into bitcoin investment do that he can use his discretionary income to invest in bitcoin and build up his emergency funds, reserve funds amd float funds along with his bitcoin portfolio.
I don't know if I am right but I feel that only the DCA method can be used to invest in bitcoin and build your bitcoin investment gradually, and at the same time build your emergency funds from the left over of your discretionary income for those new beginners who are not earning much and don't have bulk cash available to use in startingtheir bitcoin investment. This is why I love the DCA strategy but if it can be mixed with buying at the dip when you are prepared, you will get a better result.
