There's a ton of speculation about today's maintenance window at @GDAX and that assets like $ZRX, $BAT or $REP may be added to GDAX or even @Coinbase. As an owner of these tokens, I would love for this to be true, but allow me to explain why this is categorically not possible. This thread is also useful to understand the key changes that have happened at @Coinbase in relation to new asset introduction, since $BCH was introduced in December of last year... It's also my first tweetstorm.
