All altcoins will be replaced by sidechains.
All altcoin use cases can be superseeded by sidechains, thus altcoins really won't have any use-case. I'll prepare my popcorn once sidechains become viable.
Price target of this week; $1600-$1800.
That is a pretty broad range.
It is, and so was $1200-$1600 and yet here we are.
If we get significantly above and beyond $1,600 (on Stamp, of course) - let's say above $1623, then we are going to have a decent likelihood to be moving into testing the resistance in the $1,800 to $2,000 price territory... though it could take anywhere between a day or two or a few weeks to get to the $1,800 to $2,000 price range.
BitFinex is about to announce 'news' this Monday and the price is already ~$20 away from its 3d high or ~$60 from the ATH. Coinbase and Gemini are also above $1600 whilst Bitstamp isn't far from it. I think that the sentiment is still very bullish.
