How many coins needed to stake?

I am new to staking, and thus inquiring on how many coins of Cardano one needs in order to receive staking capabilities? Is there a minimum number of Cardano needed? And when will this POS begin?

Hi Dude,
Staking terms have not been finalized (or published outside at least) yet. My suspicion is you can stake with only 1 Ada, but of course your odds of a reward with 1 Ada are pretty low.
There should be a lot more info (rewards, pool vetting, etc) starting in February as Shelley get’s closer to roll out and ‘rewards era’ begins!

Are you going to stake on a Node yourself?
