I like this MoneroV has limited supply of coins and MoneroV will implement new protocols.
To get Moenrov I will need to buy Monero and transfer it to my wallet. After March 7 on this purse appears Monerov 10 times more. Did I get it right?
March 7th is a different hardfork of Monero. (without the other chain staying alive though

)
The snapshot for MoneroV will be at block 1529810.
Other than that, yes, in the MoneroV wallet you will then have 10x the balance you had before in the Monero wallet.
