We need a net new $28tn for BTC. Where would this come from?

What am I missing with this $1.5m target price by 2035? Why are people so 💯 certain? Help me believe before you’re mean to me please. I do actually own BTC. About 8% of my entire net worth is tied to the price of BTC. But I just can’t see it hitting $1.5m that quickly under any circumstances. Unless the USD collapses maybe and $1.5m USD isn’t a big deal in 2035 🤷🏻
