In the beginning, Entrecard allows us to sell the credits or transfer to anyone without any control. Then, they have controlled credits and stop allowing users to sell credits. Many active bloggers have left this network because of this issue. Personally, I have been getting $50-$100 monthly just from selling EC credits. In developing countries like India, Indonesia, Malaysia, etc this amount is very helpful especially for those who work from home. About 2 years ago, my main blog income is from entrecard credits. I have 3 computers to support dropping for 6 blogs in 2-3 hours a day dedicatedly. The value of EC credits dropped tremendously because more bloggers involve in this trading. It was $5-$6 per 1,000 EC in early days, and then dropped to $1-$3 within few months time. Then, Graham Langdon stopped us from selling EC credits. They had option to withdraw money using “Cashout” but it is not successful either.
Recently, Entrecard have launched third party market where you can buy or sell using EC credits. Market is a common place in Entrecard earlier too. The only difference I can see from this new third party market is users able to sell or buy Entrecard credits. I can see some even sells $0.50/1kEC in this market. Of course that is the lowest rate I can find here. On average it is going at $1/1kEC at current rate. It is definitely going to be a new way to earn money online for bloggers. So, this is kind of shout out for all ex-Entrecarders out there who left the community for whatever the reason. They just got better now by allowing us to trade the credits for free without any control over it. Come and join back Entrecard and earn an additional income from your blogs.
As for prediction on rate of EC credit, the value could drop lower than $0.50 soon because there is a credit limitation cap to 100k for Entrecard accounts (including all your linked blogs). We can see more Entrecarders rush to sell their EC for cheaper rates. Anyway, if your blog is still new, you may not have alternate opportunities to make money like other top bloggers. At least, you can monetize your blog using the credits you earned from Entrecard. For example, if you could drop 300 cards a day and earn 50 more credits from blog post and advertisement, then your daily credit income is 350 per day. Within a month you can gather 10k credits which can be sold at $10 (current average rate). If you have 5 blogs, then you could easily get $50 extra income from your blogs. By doing this, you are also increasing your blog traffic and have higher chance to get good page rank in next update which will open more opportunities for your blogging income.
