It was only necessity that forced me to sell my wife's jewellery.
In 2022 I lost a lot on several investments, most notably $4000 worth of cryptocurrency during the Luna crash and $1500 worth of crypto during the FTX bankruptcy. So right now I don't have enough liquidity in my pocket to invest. So I am forced to sell my wife's hobby jewelry even though it is very difficult.
Sorry about your losses. But if you see this step you want to take now as a way to recover what you have lost, then you may be doing the wrong thing or investing the wrong way, before buying BTC, you must understand what you are doing and for how long you intend to hold, from your calculations you believe by 2024 you would "cash out", but what if you have to wait for much longer, can you hold on and still manage to foot your bills. Considering the amount you said you have lost in just a short time, investing too much into BTC is a bad idea, you can slowly buy BTC through dca.
From the 'moral' side of things, convincing your wife to sell her jewelries so you could invest in BTC is wrong, and i am sure you said it to her in such a way that profit is sure by 2024, try explaining everything to your wife perfectly, including the risks and see if she would affirm to the decision any longer.
