Some qualities do differ, like in crypto trading with the help of blockchain you can keep the history of transactions transparent and these transactions cannot be deleted or changed in any way. This helps build trust between one another in the crypto world. In traditional financial trading, there are ways to get past these things, so there is a lack of trust between one trader and another.
The transactions cannot be hidden from the admins of the platform and from the trader's followers. The platform will not allow that to be an option because we want the users of the platform to have mutual trust, and the only way to do that is by having all transactions be done through the blockchain.
