I choose the 4th option which is not in the list. Mining using purchase of hashrate nicehash or miningrigrentals because:
-minimal risks.
-income here and now.
It`s cloud mining, it`s on the list.
Staking is the new kind in my opinion. Proof of work systems are very old, and they cost a lot. But proof of stake (nodes) doesn't really require much. I personally invested in a coin which will have masternodes in the future. I hope to earn monthly income with it.
I`m staking few coins nothing big, I`m thinking to invest more in those coins I already staked, and I`m always looking for new coins for staking. I think its a nice way to have some passive income.
Nice thread anyways, its interesting to see what people prefer to do, mine or stake.
