I heard about something that happened some time ago where a man won a huge some of money in gambling and he decided to save the money in a particular bank the money was there and later on the bank was closed down and he had to go through a lot of procedures to get his own money he was paid half of the money with promise of completing the payment soon, this won't happen if you saved with Bitcoin.
Some people have had their funds in CEXs and it shut down, leading to heavy financial loss. Many people who has their bitcoins and Ethereum in FTX collapse, especially bitcoiners may be really unhappy when they start the proposed repayment because according to what I read somewhere, they plan paying $2500 per eth and $20k per Bitcoin which was the worth as at the time of it's collapse in 2022.
Having funds in CEX is very unsafe, you only have total control over the coins in your decentralized, open source wallets.
There was a story where a banker sends customers details to scammers and they have succeeded in scamming a lot of people, this won't happen if you save with Bitcoin.
It is worthy to note that Bitcoin operates on a decentralized network, This means no central authority or government controls it, Bitcoin gives full financial security and you have privacy you alone controls your money, when you invest in Bitcoin you won't have to worry about government policy, in the time of war or conflict your investment is secured.
Beyond decentralization and avoiding exchanges, how we suggest our seed phrases matters a lot. We didn't screenshot them and save in h gallery since there are legitimate apps that can scan our gallery and have access to our images, neither should we store them online since online accounts can get hacked and our seed phrases compromised. It's better we store them securely offline and limit people's access to it's location environment.
