Easy, you have 1000s of some shit-coins, where if you sell it off slowly, you'll get a reasonable value for it. However, if you try to sell it quickly ... you'll eat through any reasonable value in minutes. For example, say you have 100 coins. There are 20 people willing to give you 100 bucks, so you sell them to those people, then there are 50 people willing to give you 50 bucks, and the rest are willing to give you 10 bucks. We'd call the 50 people willing to give you 50 bucks 'resistance' (at least that is what it is called in FTX-land). So, I cash out for (20 * 100)+(50 * 50)+(30 * 10) = $4,800. A nice slow sell-off could result in selling the whole 100 coins for $100, or $1,000,000, whereas dumping it, like in this example, can result in "losing" a ton of "potential cash." I was dealing with volatile coins, so often there was very little resistance (if any) to retain any kind of value.
