MoneroV requires Monero holders’ private keys to receive tokens from the airdrop, leaving many to question the safety and privacy of MoneroV’s launch. MoneroV has recommended solutions to these risks, but many are convinced these issues should not have arisen in the first place. While the MoneroV project is open-source, the MoneroV wallet is not, meaning the wallet source code cannot be audited prior to launch. [/b]
That's false. This is like every fork, always remove your original coins to another safe wallet, before you try extract forks. You don't have to risk anything to use moneroV if you take precautions. If you don't do any precautions you'll have a short stay in crypto anyway.

The issue is the following. Let's say you are very careful. You make a fresh Monero wallet, send everything there. The fork happens. You transfer out your Monero in a transaction A using ring size 5 and real input 1 with decoys 2, 3, 4, 5, 6. Now you do claim your forked coins, again transferring them with ring size 5 and real input 1. Since decoys are selected randomly, this transaction will have different decoys 7, 8, 9, 10, 11. Now the NSA looks at both the Monero and the forked block chain. They will see these two transactions. They have the same key image, so they are easy to find. The will also see, that each uses 6 input, but 5 of them are different. That means that the real input must be 1. You may think that this is okay. It was just a throw-away wallet. However, this input of yours will be used as a decoy for the transactions of other people. Since the NSA now knows exactly where your input was actually used, they can remove it from the decoy sets of all those people. If many people claim their forked coins in this way, many many decoys become worthless in this way. This will allow the NSA to identify even more real inputs (for example they already know all the decoys of a transaction were already really used somewhere else), which then also become worthless as decoys. This means that everyone's privacy is negatively affected by the people who claim their forked coins.
