Whether you call it a "one-time levy" or the assets being seized is splitting hairs. The result is the same. Given that the money had already been taken, it would be hard to apply the levy more than once.
> Most of this money belonged to foreigner using cyprus as a tax haven.
This is just a smear against depositors. They had their money in a Cypriot bank account and had a reasonable expectation that it would stay there. Their intent for moving the money into Cyprus is irrelevant and certainly doesn't give anyone the right to arbitrarily seize assets.
> Those who lost 3 Millions in the process were given a 7 millions discount on buying the Cypriot citizenship.
How generous. This is like buying a faulty good and being given store credit for the same store as compensation.

But now let's provide some context here, the EU had to bailout Cyprus as a consequence of the US subprime mortgage crisis. So the EU had to clean up the mess made by the US.
Though I do agree there are some rotten things on the financial side of the EU, mainly the IMF and the ECB but also that countries have to pay for the private debt of banks. But this is not so different from the rest of the world and other central banks. Though quite scaled down it's not so far from the 700 billion bailout of banks in the US and the ECB and other central banks and federal reserve buying 2.5 trillion of government debt and bank asset the largest such move ever while EU and US government were injecting 1.5 trillion in their major banks.
