Some bad advise being spread on different social media is just to make people doubt self custody,
There is nothing wrong with having doubts; it prevents you from blindly trusting, for instance, crypto wallet's developers and HW-manufacturers. After the incident with Coldcard, didn’t you start to have doubts about the reliability of such devices?
but I am making this post to remind you, or so you can also remind the Bitcoiners outside the forum that is beginning to doubt self custody, I want you'll to remember that the wallets that are attributed to Satoshi and are holding lots of Bitcoin has not yet been hacked and the Bitcoins has not been stollen.
1st, we don't know which wallet these assets are stored in. What wallets were even available back then? Bitcoin Core? Electrum?
2nd, these coins might not be "stored" in any wallet at all, as the seed phrase or private key may have been destroyed. It is impossible to steal something that cannot be hacked (because there is nothing to hack).
3rd, there are "threats" other than hacking, such as the loss of access to assets (access keys) by the users themselves, or due to external, unforeseen circumstances (force majeure).
Holding your coins in a cold wallet and protecting your key, safely keeping it offline is better than leaving your coins under centralized control.
In my view, neither option is 100% reliable. Each one carries its own risks (drawbacks) that can't be eliminated.
Post like this will only convince some greenhorns to believe that centralized custody is the best option.
There is no single "best" choice. Each storage method has its own advantages. Therefore, rather than agonizing over the dilemma of "which is better", it is best to employ a hybrid approach - utilizing both custodial and non-custodial methods for storing your assets.
I agree with the view that, for the majority of cryptocurrency owners, self-custody is ill-advised - not everyone is capable of shouldering such a level of responsibility for their assets or ensuring an adequate standard of security.
How can you imagine someone who is incapable of taking on any responsibility managing their own assets? Think of those friends or acquaintances who can’t even remember where they tossed their socks the night before, and then can’t find them the next morning.

Can you picture such a person independently safeguarding a large sum of cryptocurrency? An owner like that would almost certainly end up losing everything due to their own negligence.
Therefore, entrusting one’s assets (or a portion of them) to professionals capable of maintaining a high level of security is a more reliable approach. Ideally, such a service provider should also be legally obligated to compensate clients in the event of theft or loss (much like in the traditional banking system) and should offer deposit insurance.
The barrier to entry for cold storage and hardware wallets is extremely high, and a single moment of carelessness can leave you vulnerable to hackers or costly mistakes.
I disagree with that. The barrier to entry for using wallets and hardware devices is currently very low - they have been made as simple as possible for users. There are numerous mobile apps available, and using a hardware wallets requires nothing more than pressing a couple of buttons.
Fatal errors stem from a low level of technical literacy among users, who, in most cases, are unable to independently ensure a high level of security for the storage of their assets. The owner of the assets will always remain the most vulnerable link in the chain of secure storage.
Just look at the recent on-chain transaction where a user lost a fortune due to a massive fat-finger error on gas fees.
But this doesn’t make self-custody of assets a bad thing (for everyone), it’s only bad for one specific type of user: idiots.

Not everyone is like that, right?
I know the counterargument: people always bring up Mount Gox and early exchange hacks. But much like traditional banks in their early days, exchanges had growing pains. Today’s major platforms are vastly more mature in their asset custody and security infrastructure than they were years ago.
That is partly true. However, recent hacks suggest a somewhat different picture, take the Binance hack, for instance. Yet, even here, the human factor plays a role. And if we look at the FTX case (have they even returned user's assets yet?), the source of the problem for users turned out to be the platform itself, specifically, the incompetence of its management. In other words, asset owners (who were unable to ensure the secure storage of their holdings) handed them over to others who were equally incapable (in this instance, failing to provide "financial" security, given that FTX, as you may recall, went bankrupt).
