Bitcoin’s Key Support Level Identified by Analyst as ‘Line in the Sand’

Bitcoin trades near the crucial $81,500 level, a key psychological and technical point.

The leading cryptocurrency is trading near a crucial psychological and technical level of $81,500, as highlighted by on-chain analyst MorenoDV.

Who’s Still Willing to Hold?

“If Bitcoin holds above the TMMP ($81.5K) while AVIV stabilizes (0.8-0.9), it suggests investors are absorbing supply and defending their cost basis.

This level corresponds to the current value of the True Market Mean Price (TMMP) indicator. It reflects the average purchase price of coins by investors, excluding miners—essentially, the entry point of major capital into the market.

According to the expert, the $81,500 level is a kind of “line in the sand”:

• as long as the price remains above it, investors feel comfortable, viewing dips as buying opportunities;
• if the market price falls below, the level becomes resistance. Investors use any rebound to sell and break even.

The second indicator, the AVIV Ratio (active versus realized valuation), indicates a transitional mid-cycle phase. The market is neither collapsing nor growing aggressively. The price moves sideways, and volatility decreases. During such times, investors rebalance portfolios, and “weak hands” exit the market.

MorenoDV outlined two scenarios:

• Bitcoin holds above the TMMP ($81,500), and the AVIV ratio stabilizes between 0.8-0.9. This would confirm investors’ readiness to defend positions and maintain the upward trend;
• the price settles below the average purchase cost. This would undermine participants’ confidence and lead to seeking demand at lower levels.

According to the expert, the market is currently addressing the main question: are investors willing to hold assets at the average entry price?
