Yes you should add a warning. Because BTG website
https://bitcoingold.org/ removed the link but it is still circulating from old forums posts and its linked on Google and people are still falling for this scam and not only losing their BTC but they are losing every single coin they own if they import a seed like an Exodus wallet because that wallet houses many different coins.
In my opinion people shouldn't withdraw until more exchanges support the coin. So far the only large exchange is Bittrex. I am waiting also for Poloniex and Bitfinex to enable deposits of this coin.
I withdrew my coins straight to bittrex and sold them no problem. Not to say my experience is indicative of others', just saying I wouldn't expect problems from them.Apparently you can't withdraw if you don't send them identity verification, but they still let you deposit.
Bittrex lets you withdraw cryptocurrency up to 0.4 bitcoins worth a day after basic verification
basic verification is your name,surname and phone number,you will have to enter a code from the SMS they send
after that you can withdraw cryptocurrencies without any problem
if you want to enable margin trading or fiat withdrawals,you will be asked to send them docs copies and a selfie
BTG is being traded at 0.03 now,with HUGE amounts being sold and the price going down as we speak
