$NAT enhances Bitcoin's viability after the block reward halving: Satoshi Nakamoto's block reward will continue to halve, and in the long run, transaction fees must support network security. If the BTC mainchain transfers were solely based, the transaction fee market might not be sufficient to sustain ultra-high computing power. The massive economic activity generated by ecosystems like NAT will create a thriving, high-value transaction fee market, fundamentally guaranteeing miners' long-term income. @ViaBTC
