Why Developers Will Select Plasma.
Plasma is entirely compatible with EVM, which implies that developers can use the same tools and smart contracts that they can use on Ethereum. This provides ease of migration and limited risk of development.
This enables developers to make apps that look like contemporary fintech applications, as opposed to a complex crypto application. Making real users that adopt it is far more likely, and Plasma lets builders concentrate on user experience, rather than discussing wallets and fees.
