Yes, that's right, DCA is not the only investment strategy that always works and is profitable because there are so many investment strategies that can be relied on and it all depends on the habits and comfort in doing it and also finances, some even use several strategies to get more profit in the long term or change it when the market situation changes and all still aims to generate good profits. DCA is indeed very reliable and also very friendly for beginners and also those who have financial or income limitations, because they cannot buy Bitcoin in large quantities and DCA is the best solution of all that and only by making periodic purchases according to ability, the Bitcoin owned will be collected and become large in the long term. So whatever the strategy is as long as it can generate profit in my opinion it doesn't matter because Bitcoin is the best choice in any investment strategy as long as it is done properly and correctly and also comfortable in doing it.
I just had a small experience of how DCA benefits you. We read too much about DCA but experiencing it is a different thing. I created a post for this in Bitcoin section and this is the
link.
In summery, if you have something which you accumulate in DCA or in Lump Sum manner then better hodl it for long term. As in my case I have a small payments that came in the form of DCA and went up to 40% in less then a year. No bank is giving such a heavy profit.
It's also a blessing in disguise that you have Bitcoin in your custody and you forgot them (without forgetting the keys).
Talking about keys, I've seen the new trend of CEX like Binance and Bitget incorporating seeming decentralized wallets into their deliverables and those wallets have keys, just like Reputable decentralized wallets too. I would love to warn anyone who surely loves his coins not to in any way preserve his coins in CEX wallets, Do not be deceived, they have control over your coins if you leave it in their wallets.
It is advisable to use Reputable ones which are open source like Electrum, Blue wallet e.tc to have more controls over your coins. Anything from CEX is not decentralized, no matter how they paint their story,
BE WISE.
Perhaps they are gradually realising that more and more people now prefer holding their bitcoin in their personally wallets so they are also trying to create something that will make such people feel at home in keeping their money in what look like self-custodian wallets but may really not be it. As long as the wallet was created via the centralized exchanges, I will not be confident to trust it neither will I advise anyone to trust such wallets. The question to ask is what will be the gain of those CEX promoting such wallets through their platforms?
We should always remember the phrase " not your keys, not your coins" and like I said before, so long as the wallets are made through the CEX, I will never trust whatever private key they give.
