wish I could have bought ETH the time they listed this thread, feeling bad now! That's a fantastic growth.
Don't feel bad there is still chance to catch this train huge space to grow more strong in future. If you have some reserve than you can buy this right now in long term you will be satisfied with this.
don't be so sure. Ethereum is great, but there's always a threat from new technologies that are emerging right now. Most of the ongoing ICOs are scams, but some might become a better smart contract platform than Ethereum is now.
