You can't do ETH transfers and say that you don't know gas at all. It's like you are driving car and when it suddenly stops, you say that you don't know gasoline at all.
Gas in the Ethereum network is the fee you have to pay for transferring from one wallet to another. If you set it to minimum, then your transfer won't be processed at all.
i already made a lot of tansactions, but yesterday even given more gas that needed things are not good, and i saw more people complaining
i dont know if crypto kitties still banging ethereum
Yeah, they are. But you can go to https://ethgasstation.info and check out recommended gas. The bigger problem are exchanges like Cryptoexchange and Bittrex who have temporarily disabled withdraw and deposit of ETH and Erc20 tokens.
