Friendly reminder that a 50% drop of $1000 followed by a 50% rally is $750, not $1000

Was just discussing this with a friend the other day and figured I'd share it here as well (but doubt this is new to anyone here)

50% down from a $1000 investment leaves you at $500. If the market goes up 50% again you'll have $750, not $1000 (50% of $500 is $250)

To get back to the initial $1000, your coin would have to jump by 100% from $500, which is a much longer journey than just 50%

So even though we had a massive 15% BTC rally today, the 15% drop we had recently still feels much heavier. Sure, things will probably go back up to where they were, but just a friendly reminder that the market is not as symmetric as it looks like
