I think bounties and airdrop are some of the genius creation in crypto, because it is imcomaprable to bitcoin mining, some may argue mining is not free, mining is not selling your time, mining is not selling your info, whatever they could say, but deal with it, they're all almost the same, some want to pay it with whatever resource they have, either it's computer power, info, time, opm, opr, opt etc, is it free?
So you pretty much agreed that earning crypto isn't free lol.
I think the only free one is proof of stake, because it take nothing to doubling something.
You can probably say that it's "free", but the thing with PoS is, you need money to make money. There are some security concerns with it too. You have funds on a device that's pretty much online 24/7.
Nope, I'm very much insist on my opinion, it's free no matter how anyone suggest it's not, because crypto itself isn't existed in the real world, it is only working on a virtual world, not only crypto is free, it's free of real world issues too, ok you can also suggest we are burning earth resource to generate profit, ofc every profit come with natural destruction, whatever business out there would cause pollution, noise, water, air, environmental pollution, which one is free of pollution? I think airdrop didn't make any pollution, what kind of pollution can you suggest? I think nothing, a waste of electricity? Nope! A waste of human resource? Nope! What does it take is just a click of button! And yeah it waste your energy to lift your finger and click the damn button, and it's a pollution, so it is not free.😂
When you no need to buy it, it's free, simple?😆
