Sure but it's not my motive. I did wireless hacking, writing sw that does things that IMO are not right. I could make a lot more money by still doing it and it's all legal.
I rather forget about it and start from nearly scratch learning about blockchain and hopefuly help develop it.

I'm in the same boat, actually...I ran a startup from 06-09 that was in the college/university admissions recruitment space. I competed with some really unsavory characters, and I refused to stoop to their level.

A lot of the practices were - and some still are - all legal. But sleazy as heck.

It sounds like you might actually live by one of my guiding principles: do that which allows you to sleep well at night.
