I do not know why you are linking between regulations and these complaints ?
There could be a correlation between regulation and higher degrees of corruption. I'll give you an example. I think everyone has heard of stories where paypal confiscates or holds someone's funds for no valid reason.
With coinbase we could have a perfect example of a financial platform that was legitimate and never scammed anyone before it was regulated which became corrupt and dysfunctional after regulation.
It all depends on whether similarities can be drawn between post regulation coinbase and paypal. As far as coinbase goes, I remember reading many posts on this forum written by people who claimed coinbase did them wrong. I've been here since 2012. I don't remember anyone saying anything negative about coinbase or allegations of corruption until after coinbase became regulated.
That's my attempt at correlating a link between the two. Would be interested to know what people think on this.
