Energy Wallet Voting: 0
Create inter-blockchain wallet that exchanges based on difficulty of blocks, and associated expected energy to mine
Each cryptocurrency unit represents a very different amount of energy used to mine it, which creates socio-economic crypto-inequality, as currently they are traded as if they are equal, in most cases... Wallets don't show invested energy (kWh), but can easily be made to, by legal requirement for all wallet owners to publish the sets of their public keys. (This is actually important for determining true value.)
Idea: universal wallet that works for all coins based on electricity energy invested as universal exchange rate.
