Congratulations, this is really wonderful! I unfortunately missed this moment when I left AntShares before re-branding (
In my opinion, it would be better to invest in Ethereum because it is a more coin stable now. NEO is also very well developed, but ETH in my opinion has a stable course. True, it's more expensive but it's really worth it.
NEO's advantage against ETH is the assian market and market regulations happenning there. If assians can't join ico's created on ETH blockchain, they will have to pick NEO and invest NEO based project.
