I have reason to be thankful for cryptocurrency. One of those who bought low and sold high (5000% high) is donating a fair bit.

But I won’t be buying some myself. You see, some 120 years ago western lands were the new millionaire maker. You could buy land for pennies and sell it for dollars a short time later.
And God called His people away from the money frenzy.
In all labor there is profit (Prov 14:23) but it trading there is only gain at someone’s expense. And that is why we ought not to get frenzied. But if someone wants to buy some as part of a diversified portfolio, I suppose it is not much different than stocks at the moment except that supply is limited, but demand is fickle. So I counsel against it.
