False!
Ethereum is proving itself to be what it meant to be: a smart contract infrastructure. Recent increase in ETH price was because of the ICOs gathering almost a $billion or so in the past month. For this fundings, people had to 'buy' ETH, it is not a bubble, it is actual demand. Now this ICOs are trying to exchange their 'income' to finance the projects or just to spend a little more, it is where the trouble begins, there is no more demands. Looks like a ponzi scheme, but it is not. It is a whole new phenomenon that I have not studied its every details and the market is just experiencing it.
not at all.
ethereum failed at smart contracts multiple times. DAO exploited it easily, another one caused a Canadian exchange lose 14 million dollar, recently the smart contracts caused the network to fail and get clogged up to the extent that caused all the transactions to be delayed.
as you said but partly backwards, there is no real demand, the demand was from those ICOs that forced people to buy ETH tokens and cause the bubble.
and many of the ICOs have not yet even started selling their tokens to cause the real dip. this drop is mostly because of the fails of last weak combined with bitcoin price falling, because any time bitcoin goes down all the altcoin go with it.
