You also need to take in consideration if the campaign is going to pay you directly on your desired wallet or will it be deposited on their platforms, i.e. for gambling related, there are campaigns that require you to create an account on their site and they going to deposit in directly on that account.

But remember that sometimes, you need to shoulder the fees if you're going to withdrawal it. So if the campaigns say, they're going to pay you .01 BTC, then expect less because of the withdrawal fees. Not unless the campaign manager can work out with the gambling operators that the fees will be shoulder by the company, like when I was in the FJ campaign before.
