$TAC weak buyers means more for me. Double up at $12 and again at $11 if needed. Sellers are short sighted but I'm happy to pick it up at a discount.

Bitcoin just hit $73,000, and in the last 60 minutes, over $60 MILLION in shorts were liquidated! First, market makers were hunting bulls, now they're out for bears with a short squeeze. This type of action shows how volatile and explosive the market can be when the squeeze is on. Expect more fireworks as traders get caught in the chaos. $TAC, $ENSO.X, and $SLP are up next—could be the mad pump we’ve been waiting for. 👉Click to view @NasdaqPulse for timely updates amid the volatility. This is one of those moments you don’t want to miss—watch closely!

$TAC Thats right baby! Come alive! Daddy's gains jumped a bit unexpectedly while most other positions are down. Are we off to the races? I won't sell this one till: 1. A 175% gain from here. OR 2. Well into the Alberta buildout. Whichever comes first.
