对。否则我们无法给比特币设 2100 万的有限上限，因为生成永远需要某个最低回报。几十年后当回报变得太小，手续费将成为节点的主要补偿。我相信 20 年后，要么交易量非常大，要么就没有交易量。
Right. Otherwise we couldn't have a finite limit of 21 million coins, because there would always need to be some minimum reward for generating. In a few decades when the reward gets too small, the transaction fee will become the main compensation for nodes. I'm sure that in 20 years there will either be very large transaction volume or no volume.
