What is the best and trusted wallet for lots of altcoins?
There are lots of wallets for a lot of different altcoins, just find comfortable wallets for what altcoins you have earned or going to invest in. And there are also wallets that are created by the team of different ICOs if they want their transaction to be safe, but most of ICOs are Ethereum based so it uses the ethereum wallet.
What wallet do you mean? I dont see many wallet support several altcoin. I mean the wallet that we store the private key.
I mostly store my altcoin in exchange because its not big amount and i just trade in that exchange just because its good exchange
