I came across an interesting site that offers a lot of information about both Bitcoin and Altocins.
I like the Calendar option where there is a filter and you can search for the coin you want and find important dates and upcoming events related to your search. I didnt know about this site before but it can be a nice way to keep track of what is happening with the coins you are holding. Especially if you are planning to invest in a new coin, you can check the calendar to see what news they have for this coin and that can help you find the right time to invest.
Check it out and let me know what you think, I am sure some people already know about this site.
