Yeah it's a real shame really that Hive isn't on coinbase, especially with their "rewards" they give out in certain coins to people for learning about random blockchain facts. It would've been amazing to have coinbase as an account creator itself to allow people to earn some crypto through them before "investing".
Oh well, most exchanges just care about $ and hive doesn't do too well in terms of daily volume on Binance and others to get their attention. If it doesn't get their attention they'll require money up front for listings or other things I reckon.
