Around 1 year ago there was a rumor that Solarcoin will be added to Poloniex and the Solarcoin Foundation added the Poloniex logo at their site. The price started to increase rapidly reaching ~ 0.25$ per coin ( 0.0004 BTC per coin). We were thinking that once Poloniex add us the price will go up arround 0.50$ to 1$ per coin... All was going well until Poloniex tweeted that they don't have plans to add Solarcoin and asked their logo to be removed from the Solarcoin.org site. It was a big misunderstanding caused by someone from the Solarcoin Foundation and since then Poloniex "bad" opinion of Solarcoin has not changed - the price went down very quickly and is still "recovering". So far we don't know what exactly was the cause of the misunderstanding and why that happened, but the one thing that we know is Poloniex don't want to add us...
There is a Dev fund and Generator Pool that dwarfs the coin in Circulation. This is why Poloniex won't list it. We know that Solarcoin Devs would never dump the coin, but only the Shadow Knows for sure...
That information is wrong. Solarcoin was listed on poloniex until 2014/2015. You claim this nonsense, I think, there is another reason why they do not want to list this coin again. It is because a lot of people has Solarcoins still in their wallets and they are unable to withdraw this coin. This is for example my account with 3000+ SLR.
