You're right , nowadays bounty have very low profitability and it is impossible to live only on this money. Although this may be a good way out for those who live in some extremely poor countries, where 20-50 bucks a month is good money. In any case, I consider it's very important to have the main work, and to use the bounty only as additional income, because the future of this industry is uncertain and it can collapse at any moment.
