Analysis of ETH, LTC, BTC currency surge in this round (2017.05-2017.06)

Stage one: ETH up, BTC slightly sideways
Now BTC, ETH rose the origin of the problem is BTC expansion controversy. Because BTC faces the problem of network congestion, it needs to be expanded. This is equivalent to turning a castle into two castles, but will cause a lot of problems, including BTC's political problems.
Another solution is to strip some of the features. Here is the isolation testimony (SW) is simple, is the BTC "witness" function and "transaction" state function isolation, thereby reducing the BTC network congestion problem. This program requires 95% of the community voting rate to reach. But the reality is far from reach.
This is only controversial about how to solve the BTC network problem, there is no clear direction. Which also led to the discussion of hard bifurcation and soft bifurcation, the former is better but the BTC currency is detrimental.
Overall, the stage BTC future is unknown, so the relative support of the BTC's bearish forces.
The ETH as the next generation of BTC, in the technical advantages of a certain lead, compared with the lack of BTC is the mass basis. But it also has a clear advantage is that there is no BTC as the expansion of the problem. At this stage the expansion of the problem just become the core contradiction, so ETH took the occasion up.

Phase 2: ETH, LTC soared
LTC is soaring from May, less than a month from 10USD rose to 35USD. There is only one good reason, that is, isolation testimony is about to activate.
With a lot of self-speculation in the suspect, in the SW issue, LTC acts as a BTC test currency. LTC changed the turnaround rate to 75%, and its own market value is small. So take it for granted, the success of the upper.
Phase III: LTC climb 40USD peak, BTC, ETH with up
LTC reached 75% of the SW vote, into the SW activation lock-in, in the expansion of the problem and further. Also began to rise above 40USD price. Since then BTC opened a long absence soaring. From the long-term 1100USD about the price, and gradually climb to 3000USD.

BTC as a vanguard of encrypted money, in general, it will drive up all the competitive currency with the rise.
At this stage, ETH will enjoy this benefit.
