Always check or read in the bitcointalk forum which is here.
I didn't know i am in bitcointalk, thanks for telling me.
hello,
i noticed that everytime an altcoin is listed at bitterex or poloniex the price is jumping. is there any way to know which altcoin will be listed next?
thanks!
I think exchanges usually announce when new coin is coming, also it is good to read announcement treads in altcoin section, you can find information where is coin listed.
Yobit is sending emails when new ico is coming too.
