I prefer to use MyEtherWallet. Easy to use, very convenient and I have never had problems with transactions. I have never heard anyone have any problems with this wallet
Phishing websites are the main problem for this MEW wallet because i have read a lot of post here saying that they were victims of this fraud. Bookmarking is one way of preventing you to be victims of this fraudulent act but there are a lot of newbies engaging in crypto that are very vulnerable to this scammers. Hope MEW could developed an APP for their wallet.
