Overlay of the two charts. ETH is all in green, BTC is all in blue. Lines are where they changed direction, with orange lines representing days when they both changed course. They seem to have been uncorrelated earlier in ETH's run but more correlated now.
Potential H&S in the making. Too early to really tell.
Could break at any time, and with the next bubble looming (in theory) it's more likely for this to break early. This market loves to take pennants and triangles to their termination points though, so we'll see.
If anything, the halving itself is associated with a temporary suppression of the price. The price then continues on the same exponential growth trend from before.
Using munkeefonix's combined MTGox-BitStamp chart I tried to find the most accurate exponential growth curve for bitcoin. The curve used by many people now necessarily uses only Stamp data, but yields a line that moves away from the historic price when placed on the combined data chart. A better fit, which includes several other low points along the price history,...
This would touch down somewhere around 424, which is on that long term logarithmic growth line including the last two bubbles. If that line breaks we would be in somewhat new territory.
Head and shoulders at Stamp. See if it holds come morning (PST).
Culminating on April 21, 2014 at around 520 USD. Drawn using the Silk Road and Mt. Gox crash lows, and the bubble top to first bounce top. Likely to break up, weakly.
Same chart as before, but with 375 as the base. Termination would be one month later, in mid May. I think the 530 base is a better representation of the main market movement thus far, but this chart is arguably more accurate and less biased.
The breakout from the smaller, green triangle, does not have much room and will likely be small. It terminates around March 14, while the larger triangle looming from the ATH terminates some time in mid-April. Triangles can break at any time, but without any major news I'm expecting this sideways/slightly down movement to continue until termination of the larger triangle.
