A Galaxy research report suggests that most of Bitcoin's second layer scaling networks, especially "rollups," may not be sustainable in the long term despite their popularity for maintaining cheap, fast, and decentralized Bitcoin payments.  Galaxy analyst Gabe Parker identified the cost of sending data as a major challenge for Bitcoin rollups.  He explained that for rollups to be successful, they need to generate significant revenue from transaction fees on their networks.  Galaxy estimated that rollups would cost $460,000 per month in a low-cost environment and up to $2.3 million in a high-cost environment to keep Bitcoin safe.
