No surprise an ETH fan is unsure of NEO but no reason why both can't succeed.
When you hold NEO in a wallet you earn GAS. Ultimately there will be same supply of NEO and GAS, but for now GAS will be in short supply. A buy imo. The question is how much is GAS worth as a % of NEO... I'm not sure.
As for the 50m remaining NEO, that's for people who build on the platform, a win-win.
I'm in and hodling. Cheers!
