Who makes money in crypto now? Bounty / airdrops are no longer relevant, trading is not for everyone, ICO is no longer profitable, mining is also not profitable enough
I myself receive income from the nodes, feels good, and I recommend you to explore this niche. Good luck to all!
I think the campaign still has advantages, we need to know in the campaigns that we do not only to get coins but there are other useful knowledge that we can develop, so don't be discouraged. Bitcoin mining also still gives good hope despite the slight results, at least this is our investment for the future.
