Crypto emergency fund

I appreciate this may be a biased place to ask this, but what are peoples thoughts/experiences on using a crypto wallet to accumulate an emergency fund. Personal Finance advice generally says to start an emergency fund, getting to somewhere between 3-12 months expenses, then invest what you can from there. For me, it feels like if I follow that rule I’ll never get to the point of savings anything worthwhile, but I’m curious to what other people have done. For context I’ve got about 10% of readily available savings kept in crypto adding a small amount fortnightly and topping up my cash savings. Thanks in advance!
