Bitcoin indeed provide financial security since its network is immutable, the network can be said to be highly secured, once the transaction is confirmed, it is almost impossible to revert or in normal cases it is impossible to be reversed. Aside from the security, Bitcoin gives us access to the global market through financial inclusion. And once we hold our BTC no one can control it aside from the one who has the seed phrase or private key, in short we can be considered as our own bank with Bitcoin. It is also given that Bitcoin is also our hedge against inflation.
I also heard of a man who was into real estate investment and because of a new policy established by their government he lost a lot of money and that was how he went bankrupt, this won't happen if you invest with Bitcoin.
Let us not forget that even with the network security and other positive attributes of Bitcoin in financial security, there is also risk involved in it. since Bitcoin is in a free market, the Bitcoin price is known to be highly volatile. If one is not careful, lack understanding of the market and lack patience, they may end up with a loss. So despite with the overwhelming positive attribute of Bitcoin, we must always be vigilant of the Bitcoin economy especially if we engage with Bitcoin as an investors.
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.
This kind of event will not happen in Bitcoin but instead, malware and hackers may go after our device security to steal our Bitcoin, so it is best to know the proper way of securing our device and creating backup for our wallets.
