Atomic wallet is really great wallet which supports many, multiple over 500+ coins and tokens . i personally use atomic wallet from 1 year as my spending wallet and it is very easy to use.
Atomic wallet supports mostly all coins and ethereum based erc20 tokens. Also, security wise Atomic wallet is great wallet. Atomic wallet has many features except storing coins.
Atomic wallet implement Atomic swap exchange feature where user can easily exchange any coins or tokens to any cryptocurrency without transferring your funds to 3rd party exchange. As Swap feature is fully decentralized, there is no risk of hack or scam.
Atomic wallet allows users to buy cryptocurrencies with credit/debit card. and it is done with the help of simplex. Atomic wallet.
All in all, User can buy, store and cryptocurrencies at one wallet only which is very great and all processes are fully decentralized. User can create all coins wallets accounts on 1 seed. and they can also extract private keys of specific coin from atomic wallet.
If you are using Atomic Wallet then you must store your backup passphrase/seed/private keys securely at 3-4 different places to avoid any loss. because atomic wallet doesn't store you keys at their servers. I will recommend you to use this wallet. but, if you want to store large amount then its great if you store in hardware wallet.
