I'm curious that you make no mention of BitShares in this post. It is the only crypto (other than Steem, which is another Graphene based blockchain) which can scale to MasterCard levels of tx/sec today. The BitShares blockchain can handle more transactional throughput than the other top 10 coins as per coinmarketcap (excluding Ripple, which IMO doesn't even belong on that list) combined - today. The entire Status ICO, which backlogged the Ethereum network for hours, could have been processed by the BitShares blockchain in uner a minute. Additionally, BitShares has price-stable smartcoins that require no counterparty trust, unlike USDT.

If you are unfamiliar with BTS, I urge you to research it, and draw your own conclusions.
