A new Bitcoin video by @Blackrock has sparked debate over its scarcity, emphasizing the 21 million cap on BTC issuance. While this limit is a key factor in Bitcoin's value, Blackrock notes there's no guarantee it won't change in the future. Some crypto developers, like @nikzh, argue that raising the cap may be necessary to maintain Bitcoin's security budget. Peter Todd, linked to Satoshi Nakamotoin HBO's Money Electric, suggested a "tail emission" could be accepted by the community in the future. The discussion highlights the ongoing tension between Bitcoin's original principles and evolving market needs.
