I support Ethereum, and have been since before it's launch, and I will continue to do so for a long time to come I am sure.
It's all about the Developers and the use case. With the right minds behind it, it's likely to have a future. Don't worry about the price for now, or proof of stake. Keep up to date with the implementation through to Casper and decide as you go along.
My biggest losses in Crypto have come when I have either cashed out at the wrong time to buy miners before the rush to grab ETH, BTC etc began, or when I sold because I was thinking I had to at a low.
If you trust the Dev's and hold like Braveheart, you stand to gain in the long term IMO.
I personally want the price of ETH to drop hundreds of dollars lower so I can keep mining them before they really explode in the next few years.
