The purpose of this infographic is to visualize the size of large cryptocurrency hacks that have occurred in the past as if they all happened today. The hacks included in this infographic extend beyond exchanges, as there were other large entities that experienced cryptocurrency hacks, such as marketplaces like Silk Road 2.0. All hacks in this infographic are displayed as if the price of bitcoin was the same when they occurred, in order to visualize their magnitudes in relation to one another.
The x-axis shows the price of bitcoin at the time of the hack. The y-axis shows the amount lost in the hack (converted to BTC for altcoin hacks). The size of each hack circle was determined by the value of BTC lost using a consistent price, regardless of the actual price at the time.
