Apparently you can. Unless I'm mistaken I thought confido (
https://coinmarketcap.com/currencies/confido/) was a scam coin. Recently the rest of Confido team was refunding their collected ETH for Confido tokens through KuCoin exchange. However some people started buying confido at a higher price than what the team was buying, eventually from 0.07$ went up to 1$ and still costs 0.34$ right now. A coin that has literally no uses, no devs, nothing and yet if you had or bought coins when it was 1-2 cents, not long ago, you could have made a x30 - 50 almost with a scam coin. Are people really this uninformed when it comes to buying coins? Is there something that I'm missing here?
The market is not rational, it is driven by emotions, this is something you need to understand very well since it is true not only for the big markets but for anything, that is why TV ads try to manipulate your emotions instead of just presenting the facts of why their product is better, so the answer to your question is yes, people can earn money with scam coins as long as there is some hype behind it.
current rate for the token for now is $0.177134 USD (-6.94%) 0.00001392 BTC (-14.97%) 0.00015519 ETH (-14.28%)
