I plan to embrace the crypto world.
I have two questions.
a) What are the safest Bitcoin, Litecoin and Ethereum Wallet. A separate wallet for each is what I am asking.(online wallets preffered)
And
b) Which is the safest Multicurrency Wallet (online wallets preffered)
Welcome on board.
Well, in my experience, i never lost my coins with Blocktrail. It's a multsig wallet. They make 3 keys: 1 backup key, 1 key with Blocktrail, and another storage online (securely, of course). For LTC and ETH i never used online, sorry

Now, for a multicurrency wallet online, i recommend for you coinpayments. "Accept over 65 altcoins now for only 0.50%" I think that can serve for you.
And remember: It's never safe to sleep in cryptoland.
