Most crypto devs don't really need their own coin or token. They are just greedy

For a long time I was thinking: "most cryptocurrencies are either scams or useless. But maybe 5% actually have a legit purpose for existence."

Well, turned out maybe as little as five or ten cryptos are there for a legit reason. I mean do this simple test:

1) choose a coin or token.

2) Question: What that coin is doing? (Besides robbing people off their money mean or making a bunch of greedy geeks rich)

3) Now the tricky part: ask yourself, couldn't the function of that coin or token be done by another, older coin (blockchain)? Or even without one?

4) If the answer to the third question is no, no other coin or token can do the said function, then comes the last question: Is that function actually useful and practical? If not, then why bother? Aside from getting rich I mean.

Now, tell me, how many coins or tokens, how many blockchains would past this test? A hundred? Fifty? Twenty? Ten? BTC and ETH? Only BTC?

Then why the fuck we have ten thousand? And how they gonna survive? And why are we wasting our money on them? Beside getting rich very fast I mean.

Now ask yourself what crypto is all about? And don't fucking tell me it is about usecase or tech.
