Yes - Nano fixes this. Nano is instantly fully-confirmed, secure and immutable. All a model needs to do is display a Nano address (or QR code) in their webcam backdrop, or on their website. They get instant notification of payments, so have the option of instantly reacting to them. So they can be interactive with their viewers in real-time. Nano is feeless, unlike Bitcoin, and will always be feeless. (Bitcoin's fees jumped to $6.25 on June 28 2019 so saying Bitcoin is currently 'cheap' doesn't really cover that.)
