what's your problem when you undergo a bounty? or can you say what obstacles do you sometimes feel lazy to do or work on a bounty? perhaps all of you have some obstacles which you can share here and might be useful for others. please share your experience 
My main obstacle when joining a certain bounty is that it took a long time or let's say months before the project end and months again for it to be on an exchange. Lots of waiting , time is irreplaceable and it's a waste of time if they do not pay for it.
