1, regulation. 2, The exchanges and 3, Mining profitability: The price of Ethereum is governed not only through speculative actions, but also by mining profitability

There are lots of new coins that are being invented every week and the numbers just gets increased and we can see from the bounty subforum how many projects are running their (pre-sale) ICO.
From what I am seeing most of them are accepting Ethereum and this is increasing the price of etherum but also is decreasign at the same time because the owners are holding a lot of these coins, just check when the price of ethereum was dumped up to 10 cents
There are many coins that are using the Ethereum platform and I think these can increase the anonymity of the users.
