Render of a 3D manufactured casing based on the Ethereum cryptocurrency logo. For the design of the casings of the Crypto Miner cars, four cryptocurrency logos were depicted: Ethereum, Litecoin, Zcash and Monero. These cryptocurrencies have a highly energy-hungry mining process, which is typical for 1st generation blockchain cryptocurrencies. The wasted energy released during the mining process of these coins fuels the crypto miner cars to drive around their track.
