It’s worth noting however that the profit didn’t come from the DCA method itself,  it rather came from the fact that the asset that was bought (Bitcoin, I assume) increased in value over time.

DCA isn’t some magic profit strategy. What really matters is whether the asset that was invested in actually grows. The beauty of DCA however is that it helps reduce the stress of timing the market and lowers the risk of buying at a bad price all at once.

For example, someone who make use of DCA to accumulate a worthless “shitcoin,” no amount of disciplined buying would guarantee a long term profits, coz the asset itself has no sustainable value.
