Results depend on the forecast horizon, the data and features used, and whether the market behaves like the period on which the model was tested. A strong historical score is evidence about one experiment, not a guarantee about what comes next.
What the research can—and cannot—show
Machine-learning models and statistical forecasting methods can perform well on particular historical samples. That does not establish that their accuracy will hold in a new period, especially when volatility or other market behavior changes. The studies discussed here test historical observations; they do not provide a prospective benchmark showing how well current AI systems predict Bitcoin prices in live conditions.
The cited studies use samples ending no later than April 2023. Their results therefore support a limited conclusion: models can produce forecasts from past data, but the available evidence does not establish dependable general accuracy across future market conditions.
Why the forecast horizon and market regime matter
Short-term forecasts can work better in stable periods
Amin Azari’s 2019 study, “Bitcoin Price Prediction: An ARIMA Approach”, examines Bitcoin closing prices over a three-year period, with a focus on one-day-ahead forecasts. It reports that ARIMA can be useful for short-term prediction when the time series behaves nearly consistently.

Longer forecasts and sharp moves are harder
The same study reports large errors when the model is trained over a longer span with differing behavior or used for longer-range forecasts. It also found that ARIMA did not capture sharp price fluctuations, including volatility at the end of 2017. Azari suggests that inputs beyond price alone may help, but adding features does not by itself demonstrate that a model will remain accurate in a different market regime.
Why impressive model scores are not proof of reliability
A 2019 technical-indicator comparison
Samuel Asante Gyamerah’s 2019 preprint, “Are Bitcoins price predictable? Evidence from machine learning techniques using technical indicators,” uses data dated January 1, 2012, through August 16, 2019. It compares generalized linear models, random forest, support vector regression, and a stacking ensemble using technical indicators. On that study’s test data, the stacking model reports:
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
- MAPE: 0.0191%
- RMSE: USD 15.5331
- MAE: USD 124.5508
- R-squared: 0.9967
These are results from that particular experiment and sample, not a current market-wide estimate of forecasting accuracy. Gyamerah also says model results should be studied across separate states. A very strong retrospective score does not show that the same model will perform as well in later conditions.
A 2024 LSTM and GRU comparison
Ali Mohammadjafari’s 2024 preprint, “Comparative Study of Bitcoin Price Prediction,” compares LSTM and GRU neural networks using daily Bitcoin price and volume observations collected through April 6, 2023. The study reports five-fold cross-validation and L2 regularization, with test-set mean squared error (MSE) values of 6.25 for LSTM and 4.67 for GRU.
Those MSE figures describe that study’s test setup. They do not establish that GRU will outperform LSTM in a new period, on another exchange, or in live trading.
Why the reported metrics cannot be ranked together
The two papers use different samples, model setups, and metrics. MSE, MAE, RMSE, MAPE, and R-squared measure different things; their values cannot be compared as if they came from a shared test. Taken together, the results do not yield a pooled estimate of AI accuracy or a prospective success rate for current markets.

How to judge a Bitcoin prediction claim
Before treating a forecast as useful, check what it predicts and how it was evaluated. These details determine whether a reported result answers your question:
- Horizon: Is the forecast for the next day, intraday movement, or a longer period? Success at one horizon does not establish success at another.
- Test design: Was the evaluation based on a chronological holdout or cross-validation? Could information from the future have leaked into model training?
- Market conditions: Does the test include both relatively stable periods and sharp or regime-changing moves?
- Inputs: Does the model use past prices alone, or also indicators, volume, or other features?
- Target and metric: Is it predicting an exact price, a return, or direction? A low error on one measure is not the same as correctly predicting whether Bitcoin will rise or fall.
- Live utility: Was performance measured prospectively, and did the evaluation account for trading costs? Historical price accuracy alone does not establish profitability.
The cited studies do not establish a current live-trading result after costs. A forecast should therefore be judged by evidence for its particular horizon, market conditions, and intended use—not by a single headline score.
