Short-term Roadmaps, Update on ETH Trades, and What Stablecoin Dominance Says Comes Next

Sep 21, 2026

Eleven days ago I sent members a brief update with an early flag. The Bollinger Bands on both majors had compressed to their tightest since the breakout, and I told you the local top might already be in, that I did not know yet, and that how price paired with band expansion would make the decision for us. Breaking down with expansion meant the local top was in. Breaking up with expansion meant it was yet to be in.

We got the latter. Both majors faked out to the downside on September 15 and 16, stopped at their lower bands, never expanded, and reversed. Bitcoin is back above $81K, Ethereum has printed a new high for the move above $2650, and the ETHU long from ~$13 that the compression put in question is alive and closing in on its first target.

Today I want to put that fakeout in its proper context, because it has a precedent I find very hard to ignore, then walk through Ethereum and a revised swing map for the ETF trades, and then spend real time on tether dominance, which I still believe is one of the clearest overall market signals we have and which is lining up with everything else from the short term to the macro. After that comes a deliberately quick Gem Score board, and a poll where your vote decides which piece of the new TechDev platform launches next issue.
