What Happens If My Exchange Does Not Support LTC M* Addresses
To avoid having the same address format as the BTC SegWit addresses, LTC has switched their address format (which starts with M*).
Thus, if your exchange does not support transfers to LTC M* addresses, please use the following P2SH Converter to convert the "M" address to a "3" address and send your LTC to the converted "3" address.
