What Could Happen to Bitcoin Scaling? A Helpful Visual

For visual learners, this is a helpful flow chart showing the scenarios that could play out with Bitcoin's effort to scale its network. 

Key players: miners and mining pools (or those who help keep the Bitcoin network stable, safe, and secure by approving transactions) 

Key dates: 

• July 17 - need 80% miners on board for BIP 91 to activate Segwit2x
• August 14 - need 100% miners on board to activate 2MB block increase hard fork 

Key implications: 

• For bitcoin protocol: either Bitcoin will scale with block size increase OR will it split into two paths: old client and new client. 
• For Bitcoin currency: expect heavy buying and selling and thus volatility surrounding key events. 
• For exchanges & their customers: expect a lot of customers buying, speculating, hedging, and withdrawing funds--which may overwhelm their capacity--expect the weaker exchanges to have potential network issues and/or freeze customer funds. Exchanges are working over time to prepare for technical glitches and increasing support staff. 
• For bitcoin payment system: secure, immutable peer-to-peer payment system remains unchanged.
