Bitcoin cycle top calculator

Every Bitcoin cycle has ended with MVRV (market value to realized value) ratios between 3.5x and 8x — 2013, 2017, and 2021 all topped in this range. This tool blends MVRV and simple trajectory extrapolation to estimate a cycle-top target for the current cycle (post-April 2024 halving).

Enter current realized price (from on-chain data, available on Glassnode), your MVRV target (3.5-5x is historical bull-top range), and sanity-check against historical cycle multiples post-halving.

Realized price is the average cost basis of all BTC in existence, calculated by summing each coin's price at its last on-chain move. In April 2024, Bitcoin's realized price was approximately $27,000 per coin — meaning the average holder bought at that price. When BTC traded at $73,000 in March 2024, MVRV was roughly 2.7x. Historical cycle tops have occurred at MVRV of 3.5-7x, implying a $94,500 to $189,000 range from that realized price base.

The Puell Multiple, Pi Cycle Top Indicator, and RHODL Ratio have all independently confirmed past cycle tops within weeks of each other. In November 2021, all three signaled extreme heat simultaneously when BTC was at $65,000-$69,000. Waiting for two or three of these independent signals to align simultaneously gives stronger exit conviction than any single model. Using only MVRV misses the timing; combining it with the Pi Cycle cross gives both a price target and a timing signal.

What MVRV actually measures

Market cap = price × supply. Realized cap = sum of BTC's UTXO values at last-move price. MVRV ratio compares current price to the average cost-basis of all BTC. High MVRV (5x+) = market cap is far above holders' cost basis = widespread unrealized profit = sellers in position to exit. Low MVRV (<1x) = market below holders' cost = bottom. MVRV has topped at 5-8x historically and bottomed at 0.6-0.8x.

Why each cycle's multiple shrinks

Cycle 1 (2013): 95x from prior low. Cycle 2 (2017): 30x. Cycle 3 (2021): 8x. Cycle 4 (2024+): projected 3-8x. Reason: Bitcoin's market cap has grown, making each % move harder. A 10x move from $65K needs $650K and $10T+ market cap — larger than gold's current market cap. Plausible but harder each cycle. Don't plan on 20-50x returns; plan on 3-5x and enjoy outperformance if it comes.

The Pi Cycle Top Indicator: what it is and when it triggers

The Pi Cycle Top uses two moving averages: the 111-day MA and the 350-day MA × 2. Historically, the 111-day MA crossing up through the 350-day MA × 2 has marked each cycle top within 3 days of the actual peak. It called the April 2021 top ($64,000) within one day and the November 2021 top ($69,000) within two days. The math is unexplained — nobody knows why these specific periods work — but the empirical record is clean across three cycles.

The indicator has not yet triggered in the current cycle (as of early 2025 data). The gap between the 111-day MA and 350-day MA × 2 serves as a real-time progress indicator: when the gap is narrowing fast, the top is approaching.

One limitation: the Pi Cycle Top only works as an exit signal, not an entry signal. It does not tell you where to buy; it tells you when the top is very near. Combine with accumulation-phase indicators (MVRV below 1.5x, Puell Multiple below 0.5) for a complete cycle framework. Enter when multiple indicators signal 'cold'; exit when multiple indicators signal 'hot.'

Practical position management through a cycle

Selling in tranches avoids the psychological trap of trying to hit the exact top. A mechanical approach: sell 10% at each of five predetermined levels. For a $150K-$280K projected top, that might mean selling 10% at $100K, $130K, $160K, $190K, and $220K. Average sale price: $160K. If BTC peaks at $180K, you capture most of the move. If it peaks at $250K, you still captured significant value at each level and have 50% remaining to sell above $220K.

Tax-location matters significantly for cycle exits. Long-term capital gains (held 12+ months) are taxed at 15-20% federal rate for most US taxpayers. Short-term gains are taxed at ordinary income rates (up to 37%). A $100,000 realized gain costs $20,000 in federal tax at long-term rates vs $37,000+ at short-term. If you bought BTC within the last 12 months, every day you wait past the 12-month mark saves real dollars. A $200,000 gain, saved from short-term to long-term treatment: $34,000 in federal tax savings at the 37% bracket.

Stablecoin parking strategy at cycle tops: as you sell BTC, move proceeds into USDC or USDT rather than fiat. Fiat on exchanges earns 0%. USDC at Coinbase earns 4-5%. On a $500,000 proceeds from cycle-top sales, that difference is $20,000-$25,000/year while you wait for the next cycle bottom to redeploy. Do not let cycle proceeds sit idle.
