Mainstream tech companies don't want to be accused of fraud, or even seen to be somehow connected with fraud. Naturally they want to avoid ICOs, that instantly undermines their credibility.

I talked to a guy who runs a successful ICO prepararion consulting, just told him 'i am a successful developer who did these and those things, is there a way to partner with you to make some leverage out of it?' and he told me that there is nothing technical in what they do, that is a machine to make money out of money, like, you bring in $150-$1000K and make $5-$10M on ICO with minimal effort and luck needed, that's it. No programming needed, they copy-paste all the minimal technical stuff needed. They never ask 'founders' if they have any programming backgrounds or if they actually plan to build anything, just to avoid embarrassment as everyone kinda knows they aren't. More, usually they aren't even under their real names, which is sensible for a criminal.

Everything blockchain-related is at best a Ponzi scheme and usually, outright fraud, except the structures that provide technical means for these frauds, like Ethereum itself.

And yes, these events make me feel that the next financial meltdown is coming. There is already too much too easy money around. If blockchain was ready in 2009, that just couldn't happen.
