Good comparison hahaha 
About selling the coins and causing a dip...
These coins have probably been sold for the most part, already being in dollars in the accounts of the FTX administrator, so I think this may actually be a good thing because some customers will be able to use the money to invest in cryptos again
If this happens, I don't think the market will dump, because there will be no selling, only buying. When people get their money back in fiat, they will start buying altcoins and BTC, which will create hype in the market.
There's news circulating about refunds being issued in fiat, possibly because they know FTX has already sold the assets and now holds fiat only. They said they made enough profit from their early investments, which is how they gathered enough funds to repay the customers. This suggests the payments will be in fiat.
