I have seen so many new DeFi projects that paid 100k+ dollars just on marketing and probably spend under 10k on development. Why? Because all these newbies are interested in buying something just for marketing, and if you do marketing very well, you do not have to do anything else, you can be copy of something else with different design and as long as you can market it you will profit.
Yes you are right for example, look at safemoon, most people have no clue what it is, most people didn't even read any docs or whitepaper, they are purely believing on the marketing wave and they only care to make a profit, buy now, sell when its higher and that’s it and safemoon is riding that.
So, it is not really that ideal situation for now, we need to get back on fundamentals otherwise market may trick us at any time for unknown reasons for sure.
