BTG transactions are fast confirmations moving from individual BTG Wallet to another.

BTG transaction from one exchange to another, can be slow confirmations from what I have examen and has mostly to do with a lag in the Network of the Exchange itself ,,and not BTG Network'' 

The best video I have found on how to import your Bitcoin Gold to BTG Core Wallet: https://www.youtube.com/watch?v=gyzwuWOkfAk

Serving as a insight tip and advise for seeing your BTG price rise faster, is to remove your BTG (with due diligence) from the Exchanges. As most will hold your Coins as asset collateraal stated per sign on agreement.

This mening the Exchange Trading Bots may (mostly do) re-submit your coins for exchange trading orders purposed for Exchange control price regulation.

If a significant portion of the BTG coins is remove from the Exchanges, then the Exchanges will have to buy-in more Bitcoin Gold. Thus expect a significant price value increase fast in consequence of BTG scarcity.
