You can deposit bitcoins using DCA method but have you ever thought that you need a strong wallet. Bitcoin storage should never be deposited in a light wallet, because you can never ignore Bitcoin, Bitcoin is a valuable asset. So the best way to save Bitcoin DCA method and even better way is to use strong wallet.
The DCA strategy is used to accumulate bitcoin, not to deposit bitcoin in the non-custodial bitcoin wallet.
I guess the earlier comment from user Hallroom was a bit cranky, given the users choice of word and how it was used in a sentence but,
I don’t see much difference when you say deposit and accumulation in this context. They both refer to the same thing.
Depositing/Receiving/Accumulating all counts towards having Bitcoin been sent to a wallet. While DCA might talk about the method or strategy by which this Bitcoin buying is been acquired as a best means for the investor, they really are just having to get these Bitcoins to some wallet in the end.
Hence, it’s ever important that you use methods that gives you some freehand to invest and you ensure your using a safe none custodian wallet for this purpose and properly secure your seed phrase or private key.
