it seems there are no restrictions for this ?

There is a demand for Ethereum, for those who slept in 2014, and the supply is limited due to the fact that most pre-sale buyers can't use terminal commands to send their coins to exchanges.  So the price is very high at the moment.  The instant a more user-friendly solution will be available for the windows users, the price will go down to about $0.30 per ether (the pre-sale value of Ether in 2014).  There are now about 30 000 ethers mined every day (5 ethers per 15 seconds), plus the 60 millions pre-sold in 2014... do the math...

In 2014, 75% of the Ether were sold to high rollers and believers. Leaving 25% of the 60 millions to small speculative "investors" who don't give shit about Ethereum.  Ether is fuel, nothing else.  It is not designed to be a currency. It only fuels contracts on the Ethereum network.  Once people get this, they will buy them only to fuel their contracts, nothing else.
