Unlike BTC, EOS can handle the capacity of Amazon on chain. In fact EOS can run AMAZON itself on EOS. From what I know only Bitshares, Dash, NEM and PIVX are ready to handle a partnership with Amazon. ETH may scale itself very well since they have a great team behind them.
The key word here is scaling. That's the #1 obstacle to blockchain. The project that handle the scaling best will rule the world of crypto. That's what EOS is attempting. It's a smart move from Amazon to notice that.
Couldn't agree more with it being a smart move on Amazon's part. Very well put.
