Why lost Bitcoin matters, why nobody knows the exact amount, and how lost private keys affect effective supply.
Lost Bitcoin is best understood as estimated inactive supply. Some coins are truly gone. Some are simply dormant. The market treats this as a supply-tightening force, but exact numbers are unknowable.
Most viral crypto posts compress a complicated system into one emotional conclusion: buy, panic, worship, or dismiss. SideGuy's job is different. We slow the claim down, separate what is measurable from what is assumed, and make the moving parts easier to see.
Bitcoin is not magic. It is a fixed-supply network with market risk, custody risk, incentive design, liquidity cycles, and human behavior layered on top.
The right question isn't "is this hype?" The better question is: what part is actually true, what part is estimate, and what decision does this information help you make?
Clarity before cost. Before anyone buys, sells, builds, or argues online, they should understand the mechanism. That's the whole point of this page. If something here is unclear, that's a SideGuy job.
