Which is the real non-pegged version of BUSD?

I know that bep20 BUSD is a pegged version, not the real one because it says so on CMC.

Yes BEP2 has low fees but that doesn't matter if it's just a pegged token. Now I've read that BUSD supports both BEP2 and ERC20. Does that mean that both of them are the official networks?

I'm going to hold a lot of money in BUSD and I don't want wrapped tokens, or pegged tokens. I want the real thing. For example, why would I hold WBTC if I can hold the real BTC instead?

Now instead of BTC im talking about BUSD. Which is the real Busd, bep2 or erc20?
