I've had mixed bag results like most, one thing I like to do that I don't see a lot doing is I really analyze the numbers and participation of something when trying to figure out what tasks are best payout potential per hour spent... some people only want to do a certain type of task, but I'm willing to go outside of the box if i see a somewhat easy task that has low participation. But as far as mixed bag goes.. I've had 1000$ airdrops.. but also bounties I've done for months that were worthless. Choose signatures carefully, try to pick ones that won't extend for quick payouts.. thats something I've definitely made mistakes on in the past.
