假设另一种场景，我把它叫“运输机难题”——假设你是一场救灾行动的总指挥，正带着一支小队坐在一架装满物资的运输机中，这是唯一一架运输机，如果没准时到就会有上万灾民饿死病死，如果最终也没到那几十万人都活不成。但此时受恶劣天气影响飞机突然损坏了，承载不了这么大的重量，必须要有一半人跳下飞机（假设不能丢物资），否则可能机毁人亡，要不要让半支队伍跳下去？   这架运输机就是比特大陆，灾区的难民就是现在的币民。比特大陆若是完蛋，对行业造成的冲击又会让一大批币民破产出局。   试想一下，有一天比特大陆真的倒闭了，那么可以预见到，矿机将挥泪大甩卖，矿工将抛售手里的BTC、BCH，BCH奄奄一息，BTC跌到新一轮谷底。虽然还会有“灾后重建工作”，但一大批人都将倒在这场灾难里，看不到明天的太阳。   作为灾民，会不会因为心疼跳下去的半支队伍而甘愿饿死病死？作为币民，会不会因为心疼被裁掉的几百上千人而甘愿看着比特大陆倒闭，忍受自己哪怕只是短期的破产？

Billions of dollars are “wasted” via proof of work, which results in a “loss of resources that’s spread out across every single cryptocurrency user, and ultimately through all the environmental externalities, every single person in society.” It‘s also pretty bad for the brand: “Like, it could mean the difference between anyone who really cares about the environment being your friend versus trying to stop you.”

I don’t get the LINE token, the Kakao token, the Telegram token and now the Facebook token. All these messaging apps DO NOT need crypto token for digital payment or in app purchase an elegant digital payment design plus LOTS of effort on merchants on-boarding can work well
