According to BitMEXResearch, the ongoing debate surrounding Bitcoin Core and Bitcoin Cash hinges on the blocksize limit and its impact on transaction speed, fees, and reliability. Critics like Roger Ver argue that Bitcoin Core's decision to keep the blocksize small has transformed BTC into something different from Satoshi's original vision, whereas Bitcoin Cash aims to preserve the 2011 Bitcoin model by increasing the blocksize. This debate reflects broader disagreements on Bitcoin's technical rules and economic direction, as highlighted in 'The Blocksize War'.

According to BitMEX Research, SegWit represents an increase in blocksize, but miners have the autonomy to choose whether or not to produce larger blocks. This autonomy presents a challenge for all blocksize limit increases, including those executed via a hardfork. This insight is crucial for traders as it affects the scalability and potential transaction throughput of the blockchain, impacting transaction fees and miner incentives.

According to BitMEX Research, miners using pre-SegWit nodes face challenges in collecting transaction fees after SegWit activation. To remain competitive and benefit from the economic advantages that SegWit miners enjoy, these miners need to upgrade their nodes. This upgrade allows them to produce blocks larger than 1MB, similar to the adjustments required for a hardfork blocksize increase. This suggests that staying technologically updated is crucial for miners to maximize their profitability in the evolving blockchain environment.
