On Hive there are always rah-rah posts about on-boarding new users - but curiously the Hive development team have not bothered to add to any of the exchanges they inherited from Steemit.
People only join things if you make it easy - and being listed on the exchanges they use is the first step.
The big breakthrough that turned Steemit into a far-eastern blogging platform was Steem getting listed on the Korean exchange UPBit in November 2017. Upbit allowed trading against the Korean Won, and shortly after Steem got listed, Steemit got a lot of new Korean users, which in turn prompted a lot of trading of Steem on Upbit (the first really big price rise was driven by UPBit).
This in turn drew the attention of other eastern exchanges - it got listed on Binance in Feb 2018 and Huobi Korea shortly after.
So, long before Ned Scott and Justin Sun made their deal, Steemit was turning into an eastern platform - the UPBit listing was the key devopment, and was probably the thing that drew Sun's attention in the first place.
When Hive forked, no attempt was made to get a listing on western exchanges like Kraken and Coinbase. The assumption was that though Hive was English-language and dominated by a western development team, that new users would join from the east and struggle with English and get downvoted by sneering whales for the lack of "quality" in their posts given all the mistakes people using English as a foreign language make.
Why would they bother with Hive when the rational thing to do is join Steemit and post in their own language.
Hive cannot grow as long as they remain an English-language platform whose main listings are on far-east exchanges whose users don't speak English.
Now we come to Blurt: if Blurt wants to beat Hive as the premier English-language platform it needs to get listed on as many European, American, African and Indian exchanges as possible, and get the listings before Hive does.
As the UPBit experience has proved, the listing on a big exchange is the key development. Once you are listed then you get the new users, increased trading volumes and price rises.
Do you think the hive developers actually want to promote hive? I have suspicions they have other goals...
