Choose the exchange pair: Litecoin vs Ethereum, in this case. Litecoin (LTC) The shift to PoS will increase the differences between Bitcoin vs Ethereum. PoS algorithms do not use miners to validate and create new blocks, instead, stakers lock their ether coins into pools on the blockchain in exchange for the right to become validator nodes. If a node is selected to process a block, they receive ether coins as a staking reward. This process is far less energy intensive than mining in a PoW system.
