We should look at some benefits of the DCA strategy as in regards to BTC, that is beyond just having a great return on investment.
There could be larger portfolio investors that may in one way or the other influence the market and many at times it is often a fault of other users who see no importance of investing in such coin/crypto project, that causes it.
So when the subject of DCAing BTC arises, besides just the profit one stands to gain and the discipline that's learned in the process, DCAing BTC will indirectly help to curb the underlying principles of concentrated power and market influence that comes with only a certain large portfolio kind-of-individuals obtaining more BTC than the rest.
While Dollar-Cost Averaging (DCA) basically focuses on managing the risks that are associated with market volatility, it can help reduce any monopsony-like effects and thus ensure that the market is favorable and less controlled by a certain large portfolio individuals.
*What do you think?
You just have to understand as well that DCA can be used by whales and not just by average investors like the majority of us. And I'm not sure if it will reduce some kind of monopoly or control by entities.
Bitcoin is too big right now to be controlled by anyone, not by government and certainly by whales. Just used DCA as you see fit and obviously, it's more of the most effective strategy that we can used here as a investors. You don't have to overthink that manipulation, just go simply invest at your own phase. If there is manipulation, it's not going to last in this market.
