300$ will be paid in tokens , am I right ? What is a current token price in exchange with normal volume?
I do not even know whether to consider participation in the competition as a permanent income? Most likely, as payment for a hobby.
This is just a bounty competition. Competition participants will receive prizes depending on their results. About any permanent income is out of the question. If someone needs a permanent income, then you can register on the Revain website and write your own reviews.
