I see that more and more investors are interested in a passive income that comes from cryptocurrencies. But, I am a little bit afraid that all these concepts: staking, crypto lending, and all form of income that is generated from nothing will end up sooner or later. When you compare mining, you have to buy mining rigs at first, then you need to pay electricity, so you spent a lot of money to mine a Bitcoin and that makes it valuable. What about staking? What you sacrifice to receive new coins?
on staking you sacrifice your coins , same as when you invest .you convert your own fiat money to crypto and you hodl that crypto to earn more crypto . you can also earn from literally nothing but some of them are not scam like dor example when you work on this forum for service or for campaigns and bounties . earning passive income is not a bubble but if you think it is , you need to sell early so that you can get a profit or get out when the bubble is about to burst .
