And perhaps we should all ask ourselves this for the sake of steadiness over volatility. Would Vitalik put all his worth on the line for the future of Ethereum? I doubt it. Any intelligent person is consistently critical of their current worthiness. Vitalik will understand that there are still big obstacles to overcome but rest assured.. right now Ethereum is looking great. If scaling issues are dealt with before a competitor arises, then we're all good. For now, be wary, put forward what you can afford to lose. Don't get hyped over insane price rises, be wary. I personally think we are priced for the confidence of the future of Ethereum more than what it currently offers. Big companies couldn't efficiently operate on Ethereum in it's current state when an overhyped ICO can clog the network.
Be confident but be safe.
