In fact, what I often see is that trade in BTC pairs is stronger than USDT, but for me it doesn't matter even though BTC pairs are removed for NPXS in USDT pairs, which are also quite stable.
Nope, for me, because NPXS is going to 1 sats and maybe lower, that why they remove trading pair with BTC. We need a smaller value with USDT pair, because lowest price with BTC is 1 sat. Seem like investor are leaving PundiX.
