If you are to blame, blame yourself for being too greedy when trying to buy dip luna when the price is on the decline and expect it to recover to make a profit. Unfortunately, that didn't happen and resulted in thousands of traders losing money.
However there is no compulsion to buy any coins in the dip price so it is a personal wrong decision, because not always buying dips will bring profits and it has been proven in the luna's significant decline which has fallen non-stop from the price of $80.
