I have 10k+ followers on twitter (many of them are into crypto area, but of course not the majority as I was active in that twitter a while ago) so I focused on taking part in Twitter campaigns where bounty managers gave x4 number of stakes to those who have 5k+ or 10k+ followers.
I think that's right, because why those who have let's say 50 or 100 followers will get the same amount of tokens as those who have thousands? So because anyway even with retweets you have limited number of campaigns you can join - I decided to focus on those where I can get maximum.
I think the biggest what I got for Twitter was around $1000 worth of tokens at ICO price (yes, I got 100 000 of tokens).. but... I can't sell them as they are available for sale only on Etherdelta and the project was not successful... But there is still a chance that they can make beta version of their project so there is a chance token price will return at least to ICO price..
In some other cases I got around $200-300 and was able to sell tokens, but usually for Twitter the amount might be around $50-100
Now I stopped taking part in Twitter campaign and one of the reasons was the small amount of tokens..
Usually Twitter is 10-15% of total campaign and the number of participants might be big, so not so many tokens left for everyone..
I.e. in one campaign there was a rule that you have to do 4 retweets a day (with 1 hour time-frame) but it looked interesting so I took part and.. received smaller amount then expected (may be bounty manager took my tokens - this also happens sometimes) .. it was $9 worth of tokens.. so really waste of time, taking to account how many retweets should you do.
In comparison, often for 1 article you can get more tokens than for the weeks of retweets...
So in article bounty I might continue with bounties, but better to focus on the projects you like.
Also some projects have "Creative bounty" - you can suggest something creative and receive tokens for that. Of course here the number of tokens will be bigger than for social media bounty.
Also good idea is to work directly with somebody from ICO team. I. e. if you might be helpful in some way for the project - you can suggest your idea or service and for your help you may receive good amount of tokens.
From many bounties I have tokens which are worth only few bucks (therefor no reason to sell and I will need to pay transaction fees) and some other tokens are not listed on exchanges.
So really bounty is like lottery, where you pay with your time)
