This is a question we always bring up when trying to kill time at work. My personal choice is telekinesis. Because you could use it to move anything including yourself. So who needs super strength if you can lift things with your mind. You could use it to build things. Make snack while sitting on the couch. The Achilles heal I fear would be that your body becomes so weak from never using your muscles that it would become vulnerable.
Or you could have the power to see into the future and predict the price of all the crypto coins. You could write the most up voted Steemit post of all time! You could use it to post the news on Steemit before it happens, and make Steemit the premiere source for information. You could let everyone know that Bitcoin will hit 30k in the year 2020 so buy now! Would you tell everyone or just your friends? Would anyone believe you? Would use use your power for good or for evil?
