The big difference between Trickle-Down economics in the legacy economy is that the right-wing purposefully funnels money into the hands of the rich.  It's fully a partisan issue pushed by the right side of the spectrum. 

With Crypto... the concept of Trickle-Down doesn't involve any governance whatsoever.  All this value is being created out of thin air and being splashed everywhere without anyone's permission or say-so. 

Ethereum is really good to transfer value on at the moment, but it has really fast blocks, making it more prone to attack. Also it's making an awkward swap to POS.  In the long run, Ethereum's main use case will be smart-contracts.  It makes logical sense that these big smart contracts will clog up the network and make transfers more expensive than say Litecoin.  Also, like I said, Litecoin has theoretically better security because they have 150 second blocks vs 15 sec on ETH.  This makes LTC 10 times more expensive to attack and double-spend on than ETH, assuming equivalent hashpower.
