Yes making bitcoin with Twitter still possible, but you have to be active in this forum and check the services and bounties sections many times daily, to joining as much as you can of this campaigns. There is nowadays few number of active Twitter campaigns, but there is a lot of Twitter bounty campaigns which pay you in tokens (you can convert it to BTC then usually)
I see many new icos that have Twitter bounties, from comments I read some people say that earning is better with them then with advertising some service on Twitter for bitcoins.
I'm active on this forum, and I can notice that is much easier to find and join some new ico Twitter bounty, when ever I open forum I see at least 5 new bounty campaigns, not just Twitter, Facebook, slack, telegram, signature. Twitter campaigns that pays participants in bitcoins are full and rare. I can't remember when is the last time I saw Bitcoin twitts campaign.
