In cryptocurrency there is POS coins, and its possible to stake coins in wallets, but its hard to get stabile staking in some coins, sometimes they stake some times not, i found out that if you want to stake a coin, that is new and has problems to get startet, it works to restart wallet, and while it syncs unlock it, and check the stake only.
This seems to work, also they need to be decryptet, and have all add-nodes.
The green light is on when you stake, you can also write getstakingstatus in Debugwallet, it should be like this:
"validtime" : true,
"haveconnections" : true,
"walletunlocked" : true,
"mintablecoins" : true,
"enoughcoins" : true,
"mnsync" : true,
"staking status" : true
If there is true, all should be good, false there is a problem!
and if you dont get any staking rewards when all is true, restart wallet, and unlock while it sync!
