They're largely ERC-20 tokens, which can be swapped for ETH on DEXes. Monero is a whole separate blockchain, and cross-chain swaps are still in their infancy and don't have markets to convert ERC-20 tokens to Monero, or definitely not with any sort of volume. The ETH will probably eventually be laundered and some of the cleaned coins sent places they could eventually be traded for XMR and eventually cashed out, but t…
"still in their infancy" implies they will eventually mature. Non-zero chance we're watching the final implosion of blockchain based cryptocurrency.
From my observation, the overwhelming majority of failures, collapses, and hacks have had a fairly limited exposure to the Ethereum-style/Solidity-based networks. This even includes the exchange collapses like FTX.
By and large Monero, Litecoin, Bitcoin, Algorand, Cardano, and the other networks that are reasonably isolated from the ETH/Solidity space have been largely unaffected by the majority of the "cataclysm" that the space has seen over the last year or two. I don't see any of these projects closing up shop in the near future and I don't see their communities giving up on them either (maybe with the exception of Bitcoin's refusal to move away from PoW or to introduce more programmability).
Odds are the cryptocurrency space is going to recede for at least a few years once the ash settles but IMHO there are too many projects that have yet to suffer serious thefts (as in actual loss not numbers go up/down) in their communities. Likewise these projects tend to also be the ones with shops that are holding sufficient operating funds in stable assets (i.e. US dollar equivalents & bonds) to continue development for the next 5+ years.
TLDR: The failures, hacks, collapses, etc have had limited effect on a lot of projects outside of the popular/flashy part of the the cryptocurrency space. Those projects still have a more or less assured lease on life for the next half a decade.
