Hey guys, I'm just wondering, what is/are the best wallets that I can use for ethereum? Or other alt coins? Can you kindly tell me, because I still don't have a wallet for altcoins. Hoping that you can help me. 
The best wallet for any altcoin is the one that is available on the official website of that wallet.Most of the time those wallets require you to run the full-node which is painstaking and should go for third party wallets then.You can even check their website for recommended wallets.Exodus is a good option supporting multiple coins.
You can use Ethereum Wallet or MyEtherWallet.
I can't promise they're the best, but they are both good imo
MyEther wallet has been involved in suspicious activities recently,I'd avoid them at any cost.I can't promise they're the best, but they are both good imo
