I recorded a video of myself to try to explain some of these issues:

Is the growth sustainable?
Ethereum price reached an all-time high of 0.0171 BTC on 12th of this month, only to experience a considerable fall soon after. Even though the cryptocurrency value is not showing any upward trend at the moment, it has scaled new heights, and it will continue to perform better than it used to in the previous months.
The cryptocurrency may not sustain this growth in a short term, but the demand is bound to grow in the long term. The ones with long term trading plans are bound to gain a lot as time progresses.
The insiders of Ethereum are ostensibly well connected professionals. They are fucking you over royally.
First of all, you should do more videos.
I was expecting something akin to the angry German kid playing Unreal Tournament, and instead I got a calm, comprehensive, thorough dictation of your thoughts with no indication of the crazy and manic sentiment your posts sometimes have

I'd like to point out a critical element that you seem to be missing/overlooking. ~35 minutes into the video you start talking about unspent transaction outputs and the issues that partitions invoke with regard to them.
Ethereum does not have UTXOs nor does eMunie for that matter, account/address balances are recorded and credited/debited as per transactions they make and receive.
Without the UTXO overhead, double spend prevention across partitions is much easier to achieve and can be done in an efficient manner.
Scripting/contracts might well be a different ball game, I haven't thought about it much, but I wanted to highlight the error with regard to transactions.
