I have already used myetherwallet for a long time. I did not have any problems with the security of this wallet yet. But I decided to use authorization through MetaMask extension to not send my private keys anymore. Even antiviruses can not save from phishing sites
yeah it good to for the future saving wallet. Now most of the people use the myetherwallect. It help to received the token payment and ethereum coin received the wallet. No one cant hack the wallet. But wallet is give your end. So don't share the key. If will be share you get more loss and don't mists the key. If need to create the myetherwallet. First you learn the rules and instruction. Then create the wallet. If good opportunity for save the coin and token. Both of price is any time to change. So follow the market price day by day.
