How much ADA required for delegate proof of work? I know still POS is not implemented but i want to know minimum ADA holding requirement.
Ada is Proof of Stake not Proof of Work, and we don’t know yet, we will have that information soon enough, within 2-3 months and the beginning of the Reward Era (Q2 2018) as per the roadmap. Keep in mind that no matter how much ADA you hold, you will be able to delegate your rights proportional to your amount of ADA to a staking pool. This way your ADA will stay in your Daedalus wallet.
