Mathematical Money | August 30, 2026 Bitcoin had a good week. It pushed above $81,000 before easing back, closed Friday around $80,000, and spot ETFs have now taken inflows for nine sessions straight — roughly $3 billion over the streak. The whole crypto market is sitting near its weekly highs. MARA did not have a good week. It was $11.34 last Friday. It closed this Friday at $10.67. So the coin is up and the miner is down, which is not how the marketing brochure says this is supposed to work. If you hold miners you've felt this before. The leverage everyone talks about cuts both ways, and lately it's been cutting the wrong way more often than the right one. Anyway. On Friday I bought 7,000 more shares. Not by choice, exactly I'd sold 70 put contracts at the $11 strike expiring August 28.
