Preselecting a currency fixes it: NOWPayments drops its own "1. Choose asset" step, so a too-small amount would leave the payer no route. That is why a preselect below the store minimum is refused before an invoice exists.
No pay currency is sent, so the payment page runs its two steps: 1. choose asset, 2. send deposit.
Hosted page shows first (no Preferred currencies set, so NOWPayments uses its own list order)
Open invoice可用：XRP, DASH, USDCBASE, LTC, USDTBSC, TRX, TON, USDCBSC, USDTMATIC, USDTTON, USDCMATIC, ETH, USDCARB, USDTARB, SOL, USDCSOL, BTC, DOGE, USDTERC20, USDC, USDTSOL
不要选：USDTTRC20 — Their amounts sit below the store minimum, and the payment page reports "less than minimal" / "amountTo is too small" instead of hiding them.
