What are the largest dead cryptocurrencies by market cap?

I’m interested in working out which cryptocurrencies are dead or dying. Perhaps you can help.

Which ones are losing interest, which ones are ghost ships, which ones are people fleeing & which ones are haemorrhaging locked value?

It’s useful to see what attrition there is in the space & to try to work out which projects might not survive a crypto Winter.

There’s a lot of hype in crypto. I’d love to know which of these projects will be around in 100 years but having some insight as to the ones that might not be able to keep the lights on in 12 months would be a start.

Thanks
