People form emergency funds when they see that a bad situation will arise. Because in the present time, people do not want to expose their investments to any danger, so they give the most importance to prudent income and emergency funds and follow the DCA method every week. As a result of regular Bitcoin purchases, they are ready to earn more financially so that they can make more money with Bitcoin investments. An investor never neglects his investment, because Bitcoin investment is long-term, so it is most important to form an emergency fund to manage it.
Speaking of emergency funds, what's the best way to make sure I don't spend my Bitcoin prematurely?
My idea is to diversify my savings. I shouldn't invest all my money into Bitcoin. I can put some funds into other profitable investments that aren't as strictly a "hold" as BTC. If I use this strategy, I might not need a dedicated emergency fund because I'll have other readily available assets. This means I can use these other funds instead of touching my Bitcoin.
The best way is to have an emergency fund and have it in your hands. An emergency fund is money that is needed immediately in an emergency and should not be kept in any other form. If you do not want to sell your Bitcoin investment before it matures, you must have a cash emergency fund. This can provide maximum protection to your investment. This is the best way to avoid spending Bitcoin in the early period. You can diversify your assets but it is not clear from your writing whether you will use shitcoins or physical assets for diversification. Since you mentioned easily accessible assets, I think the amount you should have as an emergency fund should be in cash.
