Smart Timing for Mining: A Deep Learning Framework for Bitcoin Hardware ROI Prediction

2025-12-04

AI Summary

Bitcoin mining hardware procurement faces challenges including high market volatility, rapid technological obsolescence, and strongly cyclical profitability. Existing research lacks a systematic framework for optimal acquisition timing decisions. This paper formalizes the problem as a time-series classification task and proposes MineROI-Net—a purpose-built Transformer architecture capable of capturing multi-scale dynamics of mining return-on-investment (ROI) to classify operational periods into three distinct regimes: profitable (ROI ≥ 1), marginally profitable (0 < ROI < 1), and unprofitable (ROI ≤ 0). Evaluated on empirical data from 20 ASIC miners spanning 2015–2024, MineROI-Net achieves 83.7% accuracy and a macro-F1 score of 83.1%, with precision of 93.6% for unprofitable periods and 98.5% for profitable ones—substantially outperforming LSTM and TSLANet baselines. To our knowledge, this is the first deployable, data-driven decision-support method for capital-intensive mining hardware investment.

Abstract

Bitcoin mining hardware acquisition requires strategic timing due to volatile markets, rapid technological obsolescence, and protocol-driven revenue cycles. Despite mining's evolution into a capital-intensive industry, there is little guidance on when to purchase new Application-Specific Integrated Circuit (ASIC) hardware, and no prior computational frameworks address this decision problem. We address this gap by formulating hardware acquisition as a time series classification task, predicting whether purchasing ASIC machines yields profitable (Return on Investment (ROI) >= 1), marginal (0 < ROI < 1), or unprofitable (ROI <= 0) returns within one year. We propose MineROI-Net, an open source Transformer-based architecture designed to capture multi-scale temporal patterns in mining profitability. Evaluated on data from 20 ASIC miners released between 2015 and 2024 across diverse market regimes, MineROI-Net outperforms LSTM-based and TSLANet baselines, achieving 83.7% accuracy and 83.1% macro F1-score. The model demonstrates strong economic relevance, achieving 93.6% precision in detecting unprofitable periods and 98.5% precision for profitable ones, while avoiding misclassification of profitable scenarios as unprofitable and vice versa. These results indicate that MineROI-Net offers a practical, data-driven tool for timing mining hardware acquisitions, potentially reducing financial risk in capital-intensive mining operations.
