I’m always against on this kind of decision making especially if the one being subject is important part of your life which is wedding. You are postponing your wedding just because you invest your funds on crypto which you that is too volatile. Yes the market can give you profit but also this profit of yours can be deleted instantly once the market already correct which is inevitable for a pump like this.
I personally wouldn’t do this especially if everything is already planned and you are the only postponing it for the sake of some profit while you have enough funds for the wedding. You should only invest money what you can afford to lose because there’s no guarantee on crypto investment.
OP isn't writing about wedding. He's writing about marriage anniversary celebration, which means that he is already married(at least that's what I can assume).
Spending money on stupid shit while you are financially unstable is counterproductive. OP's wife must understand that money doesn't fall from the sky (or doesn't grow on the trees) and making big expenses for unnecessary celebrations can have negative impact over the finances of the entire family. On the other hand, OP shouldn't be so confident about Bitcoin/crypto bringing him guaranteed returns. The crypto market is volatile right now and the price pump to 48K USD won't last forever.
