I was going to post about that yesterday, but couldn't be arsed.
The fact the crypto cap is so small, only 2 or 3 trillion dollars (eeek), compared to the stock market being 100 times the size, it is easy for the whales to manipulate the market.
We have already seen this happening since they really got involved in the space around November. Things that should have happened based on all logarithmic predictions, didn't. It was clearly visible then, that this had happened due to the market play of a few BIG investors playing games with the market to alter outcomes.
Eventually the market cap will be big enough that these instances will be a lot harder to wrangle. But that is a long way off, and plenty of shifty regulation can happen in the mean time.
