Many people in my country still don't believe in Cryptocurrency and would rather save or invest with local banks but the recent sad event would serve as an eye opener to them. One of the top leading banks in my country (GTB) got there server invaded by hackers, some period before it happened they where advising customers to buy their shares and many customers did, I feel so sorry for those who bought shares with them cause their money is probably gone.
Cryptocurrencies are still quite new and are not even legalized in some countries yet, so you cannot expect everyone to choose cryptocurrencies over banks. Additionally, just because a small bank in your country goes bankrupt, you cannot equate them all and assume that all banks around the world are the same.
I have been using the bank for over 15 years and have never had a problem. Not to mention, if the bank goes bankrupt, they will have a policy to compensate people for their losses because they are under government control.
Whereas investors could only lose totally on Cryptocurrency when they fail to invest on Bitcoin or other good Cryptocurrencies and instead invest on shit coins, or they save their assets on a custodial wallet instead of a non-custodial one, else Cryptocurrency especially Bitcoin is one of the best and safest investment any investor could think of.
I wonder why anyone would even think of buying shares with a local bank or saving huge part of their money with them, when they could save for a long-term with Bitcoin and make huge returns later, Bitcoin blockchain makes it very secured and the only ways an investor is at risk is saving their asset with a wallet that could easily be penetrated by hackers or fail to safeguard their private keys.
Bitcoin is still considered an asset, a high-risk investment because of its volatility and relatively small age. If we were to give a comprehensive and fair assessment it would clearly not be the safest property as you say.
Bitcoin is the safest asset? This is just an unfair assessment from bitcoin investors, nothing more, nothing less.
