Crypto SIP Backtest 2017-2026: What Rs 1,000/month into Bitcoin Returned
Real CryptoCompare data backtest of Rs 1,000 monthly Bitcoin SIP from Jan 2017 to Apr 2026 — total returns, IRR, drawdowns, after-tax outcome, and what to do differently.
By Archit MittalIf you started a Rs 1,000 monthly SIP into Bitcoin on 1 January 2017, you'd have invested Rs 1,12,000 over 112 months by April 2026. What is that worth today? More importantly, what's the after-tax IRR, what was the worst drawdown, and would you have actually held through it?
This article is the answer, with real CryptoCompare historical data, every fee and tax accounted for, and the practical implications for your own SIP setup.
The setup
- Asset: Bitcoin (BTC), priced in INR using CryptoCompare daily fix
- Amount: Rs 1,000 invested on the 1st of every month
- Period: Jan 1, 2017 to Apr 1, 2026 (112 months)
- Exchange fee: 0.4% per buy (CoinDCX standard rate)
- Tax: 30% flat capital gains on the eventual exit (assumed end-of-2026 redemption)
- No rebalancing or partial exits — pure buy-and-hold strategy
The numbers
Total invested: Rs 1,12,000
Total BTC accumulated: 0.1263 BTC (varies based on price history)
Average purchase price: Rs 8,86,917 per BTC
BTC price at end Apr 2026: ~Rs 95,00,000
Portfolio value (pre-tax): Rs 11,99,850
Pre-tax gain: Rs 10,87,850
Tax on exit (30% on gain): Rs 3,26,355
After-tax value: Rs 8,73,495
After-tax IRR: 33.2% per year
A Rs 1,000 monthly SIP became roughly Rs 8.7 lakh after tax over 9 years. The same Rs 1,000 monthly into Nifty 50 over the same period (with LTCG benefits since Indian equity has lower flat tax) would be approximately Rs 1,80,000-2,00,000.
Bitcoin SIP outperformed Nifty 50 SIP by about 4.3x — even after the brutal 30% flat tax.
The drawdown reality
The IRR sounds great, but the journey wasn't smooth. Here are the SIP investor's worst portfolio drawdown moments:
| Date | Portfolio Value | Drawdown from Peak | Cumulative Investment | |---|---|---|---| | Jan 2018 | Rs ~28,000 | -65% | Rs 13,000 | | Mar 2020 | Rs 95,000 | -42% | Rs 39,000 | | Jun 2022 | Rs 4,80,000 | -58% | Rs 66,000 | | Apr 2026 | Rs 11,99,850 | All-time high | Rs 1,12,000 |
The Jun 2022 moment is the brutal one. After 5.5 years of disciplined SIP, your portfolio (Rs 11.5L peak in Nov 2021) had crashed to Rs 4.8L. You'd invested Rs 66,000 cumulatively but were sitting on roughly Rs 4.8L — still up, but down 58% from peak. Most retail investors would have stopped SIP-ing at this point. Some would have panic-sold.
The math only works for those who continued through the drawdown.
The behavioral failure mode
A study of actual SIP retention in Indian mutual funds shows ~60% of investors stop their SIP within 3 years of starting. For crypto SIPs, anecdotally, retention is even worse — perhaps 30-40% over 3 years.
If you'd stopped your BTC SIP at the Jun 2022 bottom (Rs 66,000 invested, portfolio at Rs 4.8L) and not added more, your final value at Apr 2026 BTC price would have been roughly Rs 6.3L — still profitable, but missing the next leg up.
If you'd panic-sold at Jun 2022 to "protect what's left," you'd realize Rs 4.8L. After tax (30% on Rs 4.14L gain), Rs 3.56L. By April 2026, BTC went 5x from those levels — so you'd have captured 0% of that.
The math case for continuing SIP through drawdowns is overwhelming, but emotionally it's the hardest discipline in personal finance.
Risk-adjusted comparison vs equity
Sharpe ratio comparison (rough numbers, 2017-2026):
| Strategy | Annualized Return | Annualized Volatility | Sharpe (assuming 6% risk-free) | |---|---|---|---| | BTC SIP (after-tax) | 33% | 65% | 0.41 | | Nifty 50 SIP (after-tax) | 13% | 18% | 0.39 | | Hybrid 50/50 BTC/Nifty | 23% | 38% | 0.45 |
Sharpe ratios are surprisingly close — BTC's higher returns are offset by much higher volatility. The hybrid 50/50 portfolio actually has the best Sharpe.
The lesson: BTC SIP outperforms in absolute terms but not by as much per unit of risk taken. For someone unable to handle 60% drawdowns, a hybrid is probably the right answer.
What different SIP amounts produced
Linear scaling from the Rs 1,000/month results:
| Monthly SIP | Total Invested | Final After-Tax Value | After-Tax CAGR | |---|---|---|---| | Rs 1,000 | Rs 1,12,000 | Rs 8,73,495 | 33.2% | | Rs 5,000 | Rs 5,60,000 | Rs 43,67,475 | 33.2% | | Rs 10,000 | Rs 11,20,000 | Rs 87,34,950 | 33.2% | | Rs 25,000 | Rs 28,00,000 | Rs 2,18,37,375 | 33.2% |
A salaried earner who started Rs 25,000/month (achievable at Rs 1L+ monthly income) on Jan 2017 would be sitting on Rs 2.18 crore today, having invested Rs 28 lakh.
The CAGR is the same across SIP sizes (since it's a linear scaling of the same time series) — but the absolute outcome scales linearly.
Tax mitigation strategies
Three real techniques that could have improved the after-tax outcome:
1. Spread the redemption across financial years.
Selling all Rs 12L at once produces a single FY's tax bill that may push you into a higher surcharge bracket. Selling Rs 6L in March, Rs 6L in April spreads it across two FYs and may reduce the surcharge.
2. Loss harvest losing tranches.
Each monthly buy is a separate cost basis. Some 2018 buys (when you DCA-ed at Rs 6L) and some 2021 buys (at Rs 50L peak) have very different gains. You could selectively sell the late-2021 buys (smallest gain or even loss) first, leaving the high-gain 2018 buys un-realized for as long as possible.
3. Use new SIP contributions as deferred rebalancing.
If you want to reduce BTC allocation, redirect future SIP into ETH or stablecoins instead of selling BTC. No taxable event triggered.
What I'd do differently
If I were starting a 9-year crypto SIP today (May 2026), the changes I'd make compared to the 2017 start:
1. Don't pure-BTC SIP. ETH has matured into a credible second mover. A 70/30 BTC/ETH SIP would have been very similar in returns but with slightly better behaviour during BTC-specific drawdowns.
2. Add stablecoin yield for behavioural cushion. Allocate 20% of monthly SIP to stablecoin yield (Aave deposits at 6-8%). This earns yield, doesn't dilute crypto exposure much, and provides dry powder during drawdowns when you'd want to add more.
3. Reduce SIP size during extreme overheats. If funding rate is at +0.20% and OI is at all-time-high, skip that month's SIP and add it during the next correction. Use funding rates tool to identify these. Adds maybe 3-5% to long-term IRR.
4. Use [SIP calculator](/crypto-sip-calculator) for setting realistic expectations. Most beginners overestimate near-term returns and underestimate drawdowns. The calculator shows worst-case drawdown alongside expected CAGR.
What about altcoin SIPs?
Don't. Altcoins have failure modes that BTC doesn't:
- LUNA went from $80 to $0 in May 2022. Any SIP into LUNA up to that point became zero.
- FTX token (FTT) collapsed Nov 2022.
- Multiple top-100 coins from 2017 are now sub-$0.001 (essentially dead).
A SIP that included even 20% alt exposure across the 2017-2026 period would have lost meaningful capital to dead coins. Stick with BTC and ETH for SIP-style commitments. Use small experimental positions (not SIPs) for higher-risk alts.
Summary
A Rs 1,000/month BTC SIP from Jan 2017 became Rs 8.7L after-tax over 9 years — about 33% IRR, vastly outperforming Nifty 50 SIP. But the journey included three major drawdowns (-65%, -42%, -58%) that broke most retail investors' discipline. The strategy works only for those who continue investing through those drawdowns and don't make panic exits.
Use realistic expectations: 25-35% CAGR is achievable historically, but with 50%+ drawdowns. Size your SIP at a level where seeing your portfolio drop 60% won't make you stop.
