DLIVE have been long gone on Steem for around 2 months now and have moved to another blockchain called LINO.
There were a lot of reasons @wa7 (founder of DLIVE) said as to the reason why they decided to leave the Steem Blockchain, two of which are: Steem is not Sustainable for Streaming Platforms and Immediate Account Creation.
I don't know if the first reason is indeed true but it is indeed easy and fast to create an account in LINO compared to Steemit's faucet sign-up, in which it takes 2days to a week for one to get an account.
As to what happened to the official @dlive account (the account that got over 1 Million SP from Steemit Inc through @mrdelegation)
It's now on power-down for weeks now and all liquid Steem went directly to DLive's founder wa7,, who is also in power-down. Interpret that as you will! But many people think they only used the Steem blockchain to fund their own project and immediately left the moment they feel that they are now funded. I myself am very disappointed to this sudden and somewhat rude move by DLive.
No Dlive is not with Steem Blockchain any more.
It has moved its Whole operation to LINO Blockchain. Apparently after staying in here for this long they do now think that the idea of rewarding users in DLIVE is not upto their satisfaction and they want a better incentive or a better way to develop their user base in LINO.
The issue of creating accounts was stated by them as well. well basically they wanted to give their Live Streamers a better userexperience in their way of saying and leaving Steem Blockchain.
Dlive left to go to Lino. They used Steemit as a testing ground and played everyone as fools. By testing on steemit they made Steem by curation using Steemit inc's delegation.
Their whole aim was to build a user base and develop the app whilst making money. They would simply transfer hoping to take the user base with them. They thought that they would have a better system with Lino paying their streamers through users paying for votes.
DLive is no longer on the Steem Blockchain. They left to join the Lino platform and made an announcement at their departure about why Lino seems best for them. I think you can find them on LINO to see what they are up to but I guess the Steem platform just didn't go well with them.
