Pay some $100k to some dev to create something the slightly differs from the existing ones
Pay some millions of dollars to some marketing agency to find a way to get this shitcoin popular. A funny name, a funny icon, or some solution in search of a problem. Something like "this shitcoin can lower the transfer fees of other shitcoins and also if you hold the bag you get 69% APR"
When it launches you immediately buy it for pennies, or even directly access some premined quota (like 30% of whole distribution) that the dev left for you
When idiots buy it, raising the price, you slowly dump it
Clueless people did the staking (lock them for a year) of millions of "cat coin", worth $1 each at the time thinking that they are going to get 69% APR. They actually get the 69% APR, but the problem is that each "cat coin" after a year is worth $0.000001 each
