I am noob in the cryptocurrencies, but I use myetherwallet and I see it that a good choice because the most cryptocurrencies are based in ethereum and this wallet works with this network. I Still, I have not had issues with this wallet.
I also used myetherwallet wallet for my alt-coins because it is recommended wallet for bounty campaign and also recommended of all of my friends.
same with me, i save my altcoin in myetherwallet or can called MEW, its simple wallet and easy for beginning in the crypto like me
but be carefully to use myetherwallet because so many phising web and it so harmful
