I'm trying to sync for weeks now, Ropsten and Main network, light, fast or normal. Nothing works. I have latest version of everything and Mac. Why is Ethereum so bad but so widely used? How to fix that problem?
You must try to check about is your wallet supported the ethereum hardfork? You can try to use the simphony. and that was easy for use. vitalik siad about it's just light wallet and that will not take large size for your hard drive. You can try to visit the ethereum github page.
Ethereum is a plattform (
https://ethereum.org/).
There are quite a few wallets to store ether and tokens inside. You have to be more specific.
So you either 1) mistakenly posted in this subforum or 2) you are takling about electrum (
https://electrum.org/#home).
Ethereum wallets which are reputable do work as intended. I am not aware of any errors/bugs/disruptions.
In case of electrum, i can't really help you without more information. Do you have the official electrum wallet installed? Did you verify it?
A few more informations and the corrections of your ambiguous statements would be helpful.
I'm talking about creating smart contract inside Ethereum's wallet Mist
But looks the new dapps was disturbing anything in ethereum network. I think that it caused by the cryptokitties.
