Some of those supply numbers are wonky, but mostly the chart is really misinformed about Ethereum. I'm pretty sure STEEM lowered inflation recently and ETH can only have a max of 100mm with the current ice age. I think the DASH numbers might be wrong as well, but I'm not as familiar with that one. Eth is the only one of the lot (besides HEAT) that runs decentralized applications. It's a little weird you got that one wrong since that's almost the sole reason why Ethereum is a thing, it's a general purpose turing complete blockchain. BTS and WAVES definitely don't do decentralized applications. Ardor does child chains. Ethereum has the whisper protocol which does e2e encryption. Ethereum has multisig and its primary language is Solidity, which is javascript based. I look forward to finding out what a smart voucher is.
