Jaxx, the popular multi-currency crypto wallet and the ShapeShift platform are not going to support Bitcoin Gold.
Thus, in particular, the representatives of ShapeShift announce that they do not plan to add a brand new token to the platform via Twitter.
ShapeShift does not plan to support the Bitcoin Gold fork at this time.

Quite a similar statement was made by the Jaxx project team.

As the company details, it does not plan to support Bitcoin Gold in Jaxx, however, "monitoring the situation closely and with great interest".
The main reason for not showing support for the new forked cryptocurrency is the same as for other companies, namely the lack of fully formed consensus code, as well as the lack of implemented replay protection.
