Actually guys, Dan IS correct and pretty much everyone I am talking to seems to be saying it. Its an unlikely scenario.

This is a quote response from Reddit bringing up this point.

correction: 100% of your transactions will not go through, since the 51% attack will be mining the longer chain

Not only that but its being brought to my attention that mining pools can be used to jack up the price as well. If they all decided to charge a higher fee then nothing can really stop them.

In other words, let's say Hive account@dan has 51% of the hashes, and is trying to censor Alice. Every 2 blocks, Alice tries to send her transaction to bittrex to spend it. She has a 44% chance each time she tries to push the transaction through.

Alice's censorship at this point turns into a joint probability, where after 1 day of 72 tries (144 bitcoin blocks per day) we calculate the probability Alice will fail all 72 times with a 56% (100% - 44%) probability of failure on each try.

Basically, Alices chances of failure are so infinitesimal (1 in 1.35x10^18), that her chances for success within one day is absolute, rounding to 100% after 16 decimal places.

In this scenario, Alice is using her wallet to make money so she can do posts about the political situations in China. 3 / 5. Well the situation you describe is her wallet being made basically useless at this point. Her wallet is dead. If your transactions are not going through and they become super expensive, lets face it, that's a dead fucking wallet.

Sorry Hive account@dan, you can't censor anyone indefinitely with only 2/3 of the ethereum hashes. You'll need much more.

They can continue this attack on Alice for as long as they want. It only takes a couple months to completely debilitate a person. They cant pay for food or rent.

I say its good enough to be counted as censorship. Alice might have been better off not using a crypto like ETH to down talk the chinese government. Its not impossible. It actually makes a ton of sense.
