How to react to dips with "high cost" coins as a beginner.

Just wanted to make my first post regarding a tip I got in the Ethereum Reddit posts regarding "high cost" coins.
With high cost coins I refer to coins that have a high price per coin, for example bitcoin and ethereum.

If you're new to cryptocurrencies and see the one you invested in dip it's no fun.
Let's say you're invested in ETH at 240 dollars and you see it dip to 230 dollars. Yikes! 10 dollars gone right?
Let's say it goes down more to 220 dollars, that's a 20 dollar loss! Looking at the costs this way is very misleading as what you should be looking at are the percentages.

Let's say ETH was worth 24 dollars. Does a dip to 22 dollars feel as bad as one from 240 to 220? Or even 2.4 dollars to 2.2 dollars? Feeling a little bit less nervous now? Because that would result in the exact same difference to your total investements as a dip from 240 to 220.

Helped me a lot in not looking at the charts too much and panicking every time it goes down a dollar.

Best of luck to all new investers. Read up on your coins, don't invest more than you're willing to lose and hold it if you believe in the long term.
