there is no minimum value but to have a realistic chance to find regulary blocks u should aim for at least 200 DMD

200 DMD find on average a block every 10 days
100 DMD find on average a block every 20 days
50 DMD or less can take one or multiple months to find a block

all that average block find chance time mean active wallet in staking mode times
that means online and staking enabled 24/7


thank you
very helpful

there is a very good new about a Monero hard fork into a new private coin : MonveroV.

https://monerov.org/

MoneroV is a private, untraceable, finite and secure cryptocurrency fork of the Monero blockchain. A split will occur at block 1529810 when MoneroV miners will start to create blocks on the MoneroV network.
The new MoneroV blockchain will contain the history of all transaction up until block 1529810 and all Monero coin holders will receive 10x their XMR balance amount as MoneroV coins (XMV) after the fork.

Among other differences, MoneroV has limited supply of coins while Monero’s coin supply is infinite, and MoneroV will implement new protocols that will solve the scaling problems facing Monero and other cryptocurrencies such as Bitcoin.

Hurts now but will feel better when we find a block.
