At least provide a good argument when you say a platform is a scam or why the price will drop. Your topic title does not match with your content.
what the op said doesn't seem to be directly related to the topic used and it makes it confusing, what the desired goal can't be achieved properly.
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
Some people would buy ETH because they know it's less volatile than unknown projects. They know ethereum devs won't take their money and abandon the project.
etherum will still be a good target for the long term and you are right in your words that ethereum developers will not do anything unwise by taking their funds stored in ethereum in fact it will even make them continue to invest there.
People with less fund and looking to get rich faster are likely to bet on new and higher risk investment. It's as if they are buying a lottery ticket hoping they hit a jackpot after buying a "gem".
investing in new projects certainly needs a strong analysis and can be convincingly well, because currently many new projects are actually committing fraud, indeed to get big profits of course buying shares in new projects but of course full of risk, although there are also many successful new projects and make investors very profitable.
when you compare it to investing in ethereum, it's definitely better and more trustworthy.
