Stakes are like shares of the bounty pool. If the bounty pool has 10.000.000 tokens assigned for rewards, and 100 people get 500 stakes per week for 10 weeks, then the stake aggregate at the end of the campaign would be would be 100*500*10 = 500.000 stakes (10.000.000 tokens/500.000 shares = 20 tokens/stake). That means that 500 stakes/week would be equivalent to 10.000 tokens/week. You do not therefore know the number of tokens you will get until the campaign ends, and all the effective stakes are aggregated, and then divided into the token bounty pool.

Regardless of the above, most campaigns will not accept Newbie participant accounts, as your 40 posts will not bear a signature (which is what gives the campaign, let’s call it, visibility).
