I stakes something like 10 coins on my own wallet, and then maybe 20 or 30 more on POScoin site (forgot the actual name but you could just stake on their pools and earn a share of it).
If I'm correct, there's one staking pool for ElonCoin but that requires the fund to be sent to Custodial wallet which is a big risk. I'm not sure how delegation aka cold staking works, haven’t found too many information on it.
so, how much I can start for staking, is 1500 EMC not enough?.
1500 EMC is too low to get you a stake. You may get a block with 1500 EMC after staking one year
kidding but yeah, it would require huge time. For getting a block daily, I think with current difficulty, you would be at least requiring 2 million EMC.
However, as said above, you can stake in pool too but there's no trusted pool has listed EMC yet.
