I cannot imagine promoting a project for months and at the end, all you can get is a meager amount of tokens. Yes, there are legit projects in the crypto space, but not all legit project worth participating in.
Why am i saying this?
There are projects that only allocate just 1% of the total sale made to bounty hunters.
My concern now is, does it worth devoting one's time to a project that will be only pay you token worth less than $100 after months of participation?
I think each person should decide for himself how much energy and efforts he is ready to put in and how much money he wants to get for that efforts. When a bounty campaigne has low percentage of allocations, it can mean that this ICO is legit and that you will get paid but unfortunately rather small amount of money. If you want to gain large profit, then you have to take a risk and join campaignes that have big allocations for bounty but they that could be scams at the end. As they say nothing venture, nothing have.
