CELCIUS NETWORK : How they offer interest income on numerous coin as well as their own sell token?

So in the real world, outside of crypto i guess banks will take your money that you deposit they'll lend it out and they give you interest, right?
They just don't give you anything right. They don't give you a lot. Celcius is kind of taking that same model but instead of taking all the profits for themselves they distribute some of that profit to you in the form of interest. So you lock your coins up in there your interest compund, you make some money but you have to obviously in same ways give up custody of your assets which people have mixed feeling about.
