Centralized exchanges can freeze or close down one's account based on several circumstances, therefore it is always recommendable to keep assets in a decentralized platform, since they don't have in possession of users' private keys, and therefore can't tamper with their assets.

I will support them on this. Because I think it's only the people who wanted to sell whose accounts are normally blocked. It's good at some point.

By the way great presentation. You did great. Good luck in the contest.
