No victim = no crime. Who's the victim with regards to "insider trading"? Is Inside Trading Really a Crime?
The SEC destroys markets, it doesn't make them safer:
Madoff and the Failure of the SEC
The SEC Makes Wall Street More Fraudulent
The SEC Short Sells Us Down the River
I'm not sure that insider trading is a victimless crime. Say you and some random person each buy 1000 shares at $5k in Corporation Y. Corporation Y has been pretty successful and shares rise to $10 / each. One day a close buddy of yours at Corporation Y calls you and tells you that in 2 weeks they are going to make a negative revelation which is going to send their stock price tumbling. You quick unload your 1000 shares for a cool $10k - not bad you made $5k. In 2 weeks the announcement is made, share prices tumble to $1k and some random person has lost $4k of value in their shares. I guess you could argue that the random investor hasn't lost any money until they sell their shares and whether or not you sold your shares has nothing to do with their actions - they could have also sold at any time - but I think it's clear that you had an unfair advantage over the random investor. Wouldn't you consider the random investor a victim here? Wouldn't you be pissed if you were the random investor? This is why officers in a company are required to publicly disclose any share sales. I mean if everybody sees the CEO of Corporation Y unload their shares then it's a pretty big indicator some bad news is coming. These kinds of rules are needed in a trading market to keep the playing field level and somebody needs to enforce them. The SEC was only an example that I thought everyone would be familiar with - the point was that some rules and regulations should be in place in crypto-currency exchanges so investors are treated fairly and equally without any extra risk.
I find it strange that currently obtaining bitcoins by exchanging them for cash/credit is either a little convoluted or risky. If we want Bitcoin to be widely accepted and used then obtaining them should be simple and straightforward and exchanges where they are obtained from should be trustworthy and regulated so that people feel safe and secure in buying them.
