The recent surge in Bitcoin price amidst stock exchange turmoil and capital outflows from China has been brusquely interrupted by the new round of Bitcoin scalability dispute. Providing that neither the current Bitcoin Core team nor Bitcoin NXT can find a middle ground, the bullying of each opinion group finally resulted in a somewhat hysterical departure of a NXT founder and an authoritative Bitcoin developer. This, in its turn, disturbed the market even greater, and may have originated even more uncertainty or to some extent panic as to the cryptocurrency’s future. However, it brings good news to traders, as the Bitcoin Volatility is back again.

However, this is not the only news for the time being, as major reshuffle happened recently in the altcoins scene. According to data from Coinmarketcap.com, the Ethereum market cap gained more than 75% during the last week, reaching $200M for the first time in its yet short history.

So true, everything that goes up must go down. ethereum will have an unstable price in the coming days

There has been massive Ethereum spam from some bot accounts targeting r/bitcoin and other sub-reddits. Looks like to me that there is a large "catfishing" expedition going on, which will predictably culminate in some large dumps, driving price back to where it came from.

Or, some magic unicorn thing happened - but I think you'd hear that from some official source if it were that important.

If the bitcoin community cannot find a solution for the block size soon, people will turn to other coins. Ehtereum is built for smart contract, so it could have more usage in banking system.
