To be honest I am just speaking about buying cryptocurrency when it reaches the bottom of the price, but I'm buying some of those with my money very rarely, I prefer to do bounties and get my rewards for free.
Interesting, that is very good if you can get such amount of money from a bounty campaign that can help you financially. But that there is too much risk while working for a bounty campaign to waste your time only, because a lot of bounties campaigns proved as scam.
