The average movement of each currency is already there on the gain/loss column.

If you buy $1000 or $10 and the price move up 10%, your invested money will also move up 10%

$1000 Will become $1100, and $10 Will become $11.

I meant the average movement of all altcoins.
Meaning: If you would invest randomly would you be better off than investing with Haejins advice.

If all cryptos go up, did the average one move better than his advice?
If all go down, did the average go down stronger?
