You don't understand regulation of the traditional markets.. Regulation lets the giants manipulate and the little guy go to jail. TPTB, with their high-frequency trading algorithms that are on computers right at the exchanges, have a hard-wired pipe to the market and can do trades in milliseconds. That is enough time to front run the markets. They can dictate the price on anything at will. They make their money whether price is up or down. Then the political establishment writes laws that allow them to do insider trading, which if you or I did it, we would go to jail. That is how crony-capitalism works in the USA.
There are no regulations against people who buy low and then sell high, even in the traditional markets
High Frequency traders manipulate prices not just by front running, but by controlling the sell orders and undercutting everything and everyone in their path. They manipulate volume with matched orders and the whole 9 none of this is illegal though believe it or not
if you were an institutional trader this would actually be part of your training
you will be literally taught how to manipulate prices
HFT guys aren't "the big boys" there are thousands of mom and pop high frequency trading firms out there that spend the whole day rigging the penny stock market
the only purpose of a High frequency firm is to manipulate prices for their own benefit and they never get penalized for it because there aren't any rules against it
so i doubt we will see any changes in this market especially not with altcoins that anyone can freely create
