Why do people go in ETH now or trust ETH now when the secret to success was to buy ETH at $0.25 or $10?

When now you are better off going in projects that are like early eth for example koinos which the devs work relentlessy on daily as you can see on github but its still so cheap as eth was day1 so this is a chance to make $100k from $100 while eth is not only making the rich richer
