The $xym (Symbol) snapshot date is planned in the second week of december 2020 (new @NEMofficial blockchain which will create new defi/iot possibilities for NEM)
If we take into account that binance is doing a lot of marketing on NEM lately (give aways and trading competitions), there's a big chance @binance and other exchanges will later announce they will support the snapshot. That would boost the value of $xem a lot before the snapshot.
People who have been in crypto for a few years would remember the $nxt and $ignis snapshots, Next multiplied its value by a factor of 10 in the month before the snapshot.
My plan is selling most of my $xem bag before the snapshot date
