LOL, 51% attack on 215.09 Th/s, good luck...

It depend on the location in some parts of the Europe it is possible to pay utility bills using ETH via 3rd party service. If you are asking this to get service from ETH directly than I don't think it is possible in future too. Some people already working on this concept to bring dapps to make it flexible for all to make it more useful in all fields of life.

You still need to get 51% of the hashrate for that. And the hashrate is 215TH/s every second, 24H a day. I don't think one can choose the tx to hash for.

I don't think you understand the magnitude of what you're talking about. It's possible, but far far down on the scale of likelihood.

Hi, I think after a while the transaction will either be canceled (I'm not sure that it will be so), or it will be confirmed, the accelerators on the ETH I have never met (as I once did, I did not find it)

Indeed it's good option to check the network status before make any transaction if we need to get confirmed in matter of seconds. Now network is normally and low fee is also acceptable to make transactions.

Recently, I see that the number of transactions in the network is quite large about 65K, but Gas price remains within 2-5 Gwei. A month ago in the ETH network this figure was much higher, I think it was a manipulation.

MEW has added a new way to buy ETH - via credit card

There are a lot of good news, that's not the issue. We need to feel the impact though. Where are the applications that make our lives better and where is the scalability we all want to be true by now? If all those things kick in Ethereum can be the universal network for everything.
