Using a quick google search, I find two wallets: CoinVault and LiteVault. Which one is the most trustworthy? Are there any better ones?
Also: What's the best altcoin wallet that has a large variety of different coins?
I don't know if coinpot is a wallet but I use it to store some of my coins in faucets. so I can say that I really trust using it. Coin pot has Bitcoin, Litecoin and Dogecoin wallet, It also have a cloud mining function, if you wanted to mine bitcoin, litecoin and Dogecoin using the cloud.
about the wallet that has a different variety of coins. it really depends on what coin you wanted to store, like for example, you need to store ERC20 Tokens that you get from all campaigns, you can use myetherwallet for that, coinbase on the other hand only hold BTC, ETH, LTC. which is very trusted.
