According to the one article I found online, a lot of new crypto services are based on the ETH blockchain:
A reported 94 out of the top 100 blockchain projects have launched on top of the Ethereum network. Ethereum as of mid 2018 has a market cap of $52.3 billion USD, but that doesnt properly show its ubiquity as the leading dApp platform for developers and blockchain startups.
So I think there should be no reason to be concerned regarding the blockchain that Zeex is based on.
This is a really huge percentage, shows us how many teams have trust in the Ethereum blockchain.
Indeed.
Some other articles claim that ETH blockchain is slow (small number of transactions per minute) so that might be a culprit. :/
