I would like to give advice to developers not to use Ethereum coin, because It has low bandwidth. Look at the side of the coin of the Wave. It looks very beautiful in this application for games
The Ethereum platform is several times more popular than the Waves, I don't think this one should be changed.
The ETH platform has a number of advantages over its competitors, it is not only popular, but also the speed of transactions and small fees.
Recently, i read the news that the btc transaction is faster. Moreover, when the cost of cryptoalate fell, eth lost its price faster than BTC
