When is magi birthday?

TBH, I can't tell you. Just started depositing my PoW rewards. So far, my stats look like this (fees will be deducted when you withdraw)

I suggest checking out their thread and ask what you want to know. They mostly replied very detailed.

Regarding Stakeminers...I never used it but read some strange stories and preferred to stay away.

Valid for all PoS services: Be very careful! Even if you see coins on "your" wallet/balance, you don't have control over the them (private key). The next morning they could be lost. The most secure way to stake is your own wallet but even that's not 100% secure. I recently found a post in an other coins' thread. Someone used a dedicated computer only to stake coins and lost all of them (as far as I remember caused by a security vulnerability in Teamviewer).

TL;DR
Don't deposit too much on PoS services, they could disappear from one moment to the next. And always check details about the fees (% of your PoS earnings and a withdrawal fee are usual) to avoid bad surprises.

Thanks Sampey and welcome in our awesome Magi community!

Thanks for sharing this. Things like these makes me want to spend more XMG in it. I would definitely take a look into it. Say, any chance of getting a game where you could spend and earn XMG at the same time? That would certainly be fun, but it is just a suggestion. 

More people should mine on xpoolx.com its a great pool with a great admin. iv been mining riecoin there for some time and have nothing but good experiences.
on the off chance you do run into problems the admin is easy to get in touch with and responds within a couple hours max if not in minutes. oh and no fees so that's a plus.

That is wonderful, because I have many great ideas of a game that would sure be fun. I may not be a game designer but I do have some great creativity. How about making a mini game of Magi which would look similar to Flappy Birds? It would be called Flappy Magi and every time you make your coin fly over the pipes or obstacles, you get points just like Flappy Birds, but the difference is that you would be earning XMG by doing that. Earnings would be paid in satoshis or should I say Magoshi.
