Explain *how*.
Yes, your own coins are safe if you run a real (full node) wallet, but you do not contribute anything to the network which can't be countered by a VM instance (which could be leased by "bad" miners for a trivial sum).
It doesn't matter how many VM instances run what clients.
What matters is what fork the the coins real people are using are on.
Initially most transactions will probably be on both forks, but as both forks continue to mine, coins will be created in the block rewards that only exist on one fork or the other.
Which node we, the people actually making transactions to buy stuff and accepting transactions to sell stuff, determine which fork has value and thus by which node we choose balance the power of the miners.
