not fully interested because of since bitcoin futures appear, the price of 1 BTC keep falling down
i know this fall is not BTC futures doing, so much other bad news about it nowadays
Unfortunetely even bitcoin futures were not that popular and there was more hopes around it. But anyway the news are great. I would like the ETH futures even more than BTC because that can be simething like an analysis of the general situation arount all ERC20 ICOs made by traditional investors. That may help to determine the time when ICO bubble blow it (
or simply push this bubble clother to the edge, hue hue 
).

interested
if we compare between ETH price and ETH supply in the market, we will see higher line compare to the last year
is it overprice?
not sure but price is grow more than 4 times but supply grow in stable number
Sure. But the past year had a peak of the ICO boom (projects were picking millions while they are not worth that much). People are still investing large amounts of money but the competition between projects also became bigger. If some of the past ICOs will perform badly accorging to their roadmap or just turn into scam then the bubble may blow up. ETH is growing only because the supply is lower than demand. The bubble will definetely blow up sooner or later but the ETH futures may help to predict this moment.
