No you should not. NEO is just a temporary hype. There is nothing yet on NEO, it as all to prove, while Ethereum is established and praised worldwide. Make your choice.
That's what they all said when ETH was just $12, they kept draging the price down to $7 and fudster were all over because of the fork and it went suddenly up. I remember I have more than 600 ETH during those times after selling some after listening to all these fuds. People are going to regret this again. opportunity has been given just as ETH did and they thought its just a pump and dump.
These are different situations ETH had no analogues
