Do You have also this problem?
mining but not accepted. 50/50 is mining. What is the problem?
Sometimes your wallet mints coins, but that is not accepted by the network. So, you don't get the coins. But don't worry, after few hours or after one day your wallet will mint again with the same block of coins which will be accepted by the network. It happens in rare case.
And remember, Sprouts is very very good (and perfect) in minting from many other POS coins. Your minting can be delayed due to low priority of your blocks, but every block of coins will must mint.
To all who are thinking that Spouts is daed. I bought 2 months ago the rest of the coins on POSWALLET when 1 sprts=0.00000066 POSW. It was ca. 500.000.000 sprts = 16$.
Today my daily stake is about 30.000.000 sprt. This is ca 30$... But im not selling.
I'm doing the same thing. Around two years ago I invested about $30-$40, then Sprouts was above 100 satoshi. Now, I have +2 billions of Sprouts. You can easily calculate the price of 2 billions Sprouts. While I sold millions of coins from staking.
I sell when I get good price and when the market gets down then I buy some more coins and send it to my wallet for staking.
