Hello there !

I am just starting with Apex, I bought my first 30 K of Apex and moved them to my wallet for staking. But in the wallet it says "not staking because you do not have mature coins". What does this mean? I have to wait for the coins to mature? How long does this lasts?

I thank you in advance for giving me assistance, and sorry if it this question was already asked, I looked but could not find it. So please help an Apex noob.

Thanks!
