If you had a large amount of cryptocurrency would you prefer to keep it on an offline cold wallet or an online cryptocurrency exchange?
Certainly an option to store it in offline wallets because the online crypto currency exchange is not a wallet.
People try to be safe for their assets, so choosing to save in an offline wallet is an obligation rather than submitting assets to those owners of the Exchange.
Both have pros and cons.
For people who are pro, they think of the convenience obtained without the need for a complicated process rather than prioritizing the security and control of assets.
Online, the risk is big and needs to be avoided.
