I am trying to figure out how this works forgive me if i am naive to this subject but i am learning anyhow. So yeah with the cefi disasters going on in crypto lately i am looking to towards defi to earn on my bitcoin. But you say bitcoin and defi aren't compatible? Well i found two places that offer just that. A place called Sovryn and a place called Alex. I am familiar with how cefi interest earning works but i am not familiar with defi. So if i place my bitcoin one of these platforms why do they ask me to convert it to wrapped btc  to earn interest or whatever token they offer? How will i earn on bitcoin if it goes up and its converted to wrapped bitcoin? I want to keep my bitcoin bitcoin. i am confused by how this works. My main question probably is why do i have to convert my bitcoin to something else if i just want to earn on my original bitcoin? Doesn't that defeat the purpose of earning on bitcoin?
