As a blockchain quant analyst from Austin, I’ve traced the subtle shift in BTC accumulation: Sixty Six Capital’s latest ETF purchase of 13.5 BTC brings their total holdings to 145 BTC. This isn’t speculation—it’s structured capital reallocation. The move reflects a deliberate pivot from paper exposure to on-chain sovereignty. I analyze this not as market hype, but as a quiet recalibration of institutional risk models. Here, the data doesn’t lie—its patterns do.
