A few things come to mind but mainly:
1) the Lightning Network is super fast and can compete with traditional credit and debit card transactions during a point of sale
2) Social Media inclusion of bitcoin and LN which makes small business easy to advertise.
3) KYB/KYC rules that sometimes it takes forever to approve someone to acquire payments even if they are running a super low risk business vs bitcoin and wallet providers that can be super fast.
A lot of things to consider but for me focused on South America for now and emerging economies it feels like the right step.
