How can I earn cash without investing? Can I earn a thousand dollars without investing or buying first?
Here we go again. There other things than money that you can invest with. For example, you can invest your emotion to someone, and you can invest your time and effort on doing bounty campaigns.
For your question, no. I mean technically you can earn, but doing transactions to make those tokens into fiat would still require GAS fee or ETH. Therefore, you need to buy at least a bit of those for you to sell your tokens.
in addition to investment. we can make money by running trading and hold. because this investment is widely known to produce large profits. but still there with the trading is also very capable of making money pretty much in the future. so very good by using trading to generate profits.
