Li Qiwei: MimbleWimble takes 6-18 months on the Litecoin network

Litecoin founder Li Qiwei said in Twitter that the user "MimbleWimble can be adopted on the LTC network", deployment and testing may take about six months. After that, as long as the miner is ready, it can go online. I now estimate that it is most likely some time between 6-18 months.
In response to the user “first to ensure that the exchange approves this”, the latest tweet indicates that we have communicated with the mainstream exchanges and they will not take off the LTC. We won't take risks easily, but there will be some risks in everything.
