Great logic there. You live the rest of your life by it, must be an interesting life...

-Something as insignificant as not being able to add 2+2 does not reflect the math abilities of the person.
-Something as insignificant as not being able to hit a nail with a hammer does not reflect the house building abilities of the person.
-Something as insignificant as not being able to spot an obvious pump and dump does not reflect the money making abilities of the person trading cryptos.

Good luck
