The Blockchain bridge is Useless because there is a reason behind this. All types of bridges have common security flaw that turns Blockchain into vulnerability and hackers can attack easily.
Having risk and was exploited does not mean it is useless. There are utilities of blockchain bridges but technology and security must be developed and enhanced so that transactions through bridges will become safer considerably.
Without bridges, you will have to sell one token on one blockchain and use money to buy it on another chain. It is uncomfortable for people but if taking into consideration about risk of exploitation via bridges, I would like to do this. Also bridges charge high fee, not cheap.
And also Blockchain bridge makes things more centralized. And currently BNB 600 million dollars hack indicates that we should stay away from this.
Only Bitcoin is decentralized from founder's disappearance to decentralized full nodes and mining farms. It can not be shut down by a single person or company. Altcoins are centralized exclusively their altcoin bridges.
