I am not a fan of Reward or free token , or mostly called a Gift reward because this is at some point is a waste of time and not worth to be spending .
there are many friends of mine that use to seek for this or Bounty but now? stopped as they only Gathered shitcoins and worthless tokens /
maybe if you  have plenty of time ? then why not. but if your every minute is precious then have a second thought  and use your time for worth a spending.
