Harmony Bridge ?

Hi Everyone,

I don't have a coding background and still learning about the blockchain and somehow I come to Harmony and love it and fully committed to support this whole project, I have watched the videos and some articles but can someone explain to me ( A regular person) in simple words.

What does this bridge will do for harmony and other investor to move to harmony? and an example in a real world. It makes me confuse, why dont people just send it to DEX and swap it to Harmony token? instead of bridging

Second question, I saw the TVL and stacking numbers, it says that we have around 106,6Million locked and around 5.3Billion is stacked on validators, what is the differences between these two? When I stake to validators, does it means my tokens is locked anyway so what make the number so different?

Thank you so much for your time to read this questions, and I hope one day all the new members can come up to this post when the encounter the same questions.
