There are 2 relatively big LTC miners that have yet to upgrade to MWEB as far as I can tell. They mine to these addresses:
LaYPLuQEanVCYM9TztR9FuT3ZbTJM6wHEZ (3% hashrate)
M9Dm7zXLhAiicuXFd68Sd3ZorAt9L4NPQU (1% hashrate)
In less than a day, they will be mining invalid blocks.
据我所知，有两个相对较大的LTC矿商尚未升级到MWEB。他们挖掘这些地址：
LaYPLuQEanVCYM9TztR9FuT3ZbTJM6wHEZ（3%哈希率）
M9Dm7zXLhAiicuXFd68Sd3ZorAt9L4NPQU（1%哈希率）
在不到一天的时间里，他们将挖掘出无效的区块。
