Even though the DCA strategy is the best strategy for Bitcoin, you cannot consider it the best strategy of all time because you have some of your own strategies that are completely different and innovative compared to this strategy. Regardless of the price this method is recommended for accumulating Bitcoin but during the continuous increase in price you should review the fact that this method increases/decreases the unit price as the holding increases in your portfolio and apply your own strategy accordingly. Therefore you need to apply some of your own strategies in terms of investment that will increase the holding over time and reduce the average price.
Buddy I don't know any other strategy you feel will should apply to our bitcoin investment in other to increase our bitcoin holding apart from the regular strategies which are DCA, buying the dip and lump-sum, but responding to your first paragraph you're wrong about DCA, because DCA strategy is best strategy for bitcoin accusation and almost everybody out there consider DCA the best strategy of time, because it allows us to buy bitcoin at any fucking time regardless of the market condition since our mindset is long term holding 4 to 10 years or longer. DCA strategy also make us who are investing in bitcoin for long term to be consistence in accumulating bitcoin either on a weekly basis or on a monthly basis with our discretionary income and hold, because you can only reasonable profit from bitcoin when you accumulate a good portion of bitcoin and hold.
The DCA strategy is a great strategy for Bitcoin accumulation but to keep it going in the long term you should practice how to be active in investing in discretionary income backup funds and emergency situations. Keep the size of the floating fund and mental preparation formed so that Bitcoin holdings can be kept safe in any situation and keep the accumulation going.
I find this your comment above misleading, and sincerely speaking it is going to mislead a lot of newbies that will come across it, because I don't know why you will be advising people to practice how to be active in investing their discretionary income, their back up fund and their emergency fund, by the way is that what you where thought? Buddy you're to invest only your discretionary income in bitcoin and not the other way round, back fund and emergency fund are not to be invested, because they have there own role to play so take note.
