There are so many BTC OGs that are looking for where to throw their money.

I don't know. Depends on the Maxi. Many of them are hard to convince that anything else in crypto is worth something. But some are more malleable.

I myself will love these promo cards me self, just that I cannot afford them .

If you don't have any card with the "halving" ability I suggest you at least buy 1 BCX of the rare one, which has the ability at level 1. It's sometimes worth it, and it doesn't cost so much. That's all I have from the Halfling Alchemist too, 1 BCX.
