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. After getting a good non-custodial bitcoin wallet, you need to protect your wallet's private key or seed phrase from people and back it up in two different locations that only you know. If someone gets hold of your wallet private key or seed phrase, he or she can initiate a transaction and move your bitcoin to a another non-custodial bitcoin wallet.
I think this should be a primary thing in which anyone intending to hold BTC with whichever strategies must first put in place mostly when it involves valuable currency like BTC and holding for a long time no matter how small the investment should be a safe Wallet with private and strong security is meant to have been put in place. I think the custodial wallet has been announced severally on the forum even other wallet having similar feather and capable of holding BTC and give holder privacy as regards to security is there for holding.
I think knowledge in general is necessary and security as well this wallet is necessary because while adopting DCA as way if long time using wallet that give this security and confidence is very necessary I supported your point of view.
Using all the strategies to accumulate is pretty helpful, like now market is redish ( decrease in price) , buying the dip would be nice by spreading it because we can't actually tell howfar the dip gonna be , I'm kinda happy that there's some dip though because it would give me more chances to accumulate more bitcoin, purchasing as the price decreases. So this time around, that's just few days to the halving we should increase our rate of accumulating by being more aggressive in any way we can.
Talking about wallet safety, to me no wallet is 100% secure so one also have to handle his wallet with caution, despite how good or secure that wallet may be.
When the market capitalization is red, the tendency to buy bitcoins means you are literally making more money. If you have enough money you can set aside for dips and DCA you should be encouraged to run at the same time. To become a good and successful investor you need to experience buying and selling from all kinds of markets. If the original red letters encourage you to buy more, the green letters can encourage you to sell more these trends can be a hindrance to depositing bitcoins. So I would say that your habit of buying bitcoins at all prices (regular buying) is one of the signs of your trading success.
