Atomic Wallet being Publish0x's recommended wallet is also one of top recommendations from me when it comes to cryptocurrency wallets.
You'll know at the end why it is one of my top recommendation, but first you (my readers) need to understand what this wallet is all about.
WHAT IS ATOMIC WALLET
"Atomic Wallet is universal non-custodial app for over 300 cryptocurrencies. Secure, manage and exchange your assets right in your hand!"
HOW TO GET IT IN THE FIRST PLACE?
Obviously you need to download wallet app. Simply choose your platform be it Windows, IOS or Android (link under resource section) ATOMIC WALLET supports all major platforms.
I GOT IT INSTALLED, NOW WHAT?
You need to setup the wallet for this simply open Atomic Wallet app then proceed by setting up login password after that Atomic Wallet will create addresses it'll take about a minute to complete process.
Now you'll see 12 random words which is generated by wallet which is backup seed phrase can be used to recover funds in case of loss of device or to reset wallet in case of forgetting wallet password, so carefully back it up where it can't be accessed by unauthorised persons. Here you must swore an oath not to give this backup phrase to anyone why because if you are sharing your phrase your loosing all your funds.
That's it, it is as simple as that.
Alternatively you can use fingerprint/face-unlock for logging in to wallet for your convenience. Access it by setting icon then fingerprint/face-unlock option.

NOW I COMPLETED THE SETUP I WANNA KNOW EVERYTHING
Now that you have successfully completed the setup you'll see following screens

I'll be explaining one by one below.
WALLETS
First of all "Wallets" screen where you'll see all the coins and tokens from over 40 blockchains with 300+ custom tokens.
Just tap on coin or token you want to receive copy/share the wallet address that's it.
HISTORY
Obviously it shows history all the transactions made by you with their corresponding wallet addresses and transaction hash for you to check at your will.
EXCHANGE
Where you can exchange one coin for another coin of your choice. Provided by Changelly & ShapeShift.
Note that to be able to exchange tokens of specific blockchain (ETHEREUM, TRON, BINANCE, etc) you need to have that specific coin to bare mining/gas fee.
Disclaimer: Always check prices before exchanging. Also do your research before using this feature.
BUY
As the name suggests is the place where you may buy over 15 cryptocurrencies using visit (look in app for supported countries). Also there will be transaction fee.
Note: You may need to verify your identity to avail higher purchase limits.
Disclaimer: This is not any investment advice. If you loose your it's your fault if you benefit from it it is your talent.
STAKING
Here you may stake various coins and tokens to earn specified percentage of passive income.
Note that after staking the staked coins/tokens won't be available for withdrawal until you unstake them. Once staked coins will be held (to know for how long check while staking)
Note: For some coins you may need to wait after unstaking (coins won't appear immediately or within hours). In my case - I staked small amount of ATOM(Cosmos) to test out staking feature. After some time I unstaked them, it's been 2 weeks (as of writing this article) they are still under 'unbonding', but I haven't read about it (longer waiting) even in official guide. No issues with receiving rewards for staking though all I suggest you to claim only when you accumulate considerable amount so that you you won't loose part of rewards over fee. Also I staked TRON the only condition is you can't unstake for three days from the day of staking and no other issues (atleast when I tried it)
Bonus: For tron coin you are not only be able to stake but also receive upto 3 Airdrops.
SOME HANDY FEATURES

Tap on setting icon to open various settings options.

ADD TOKEN
It'll help you to add ETHEREUM based tokens to wallet

WALLET CONNECT
Used to connect to Decentralised Exchanges (DEX) (like loopring.io) to trade crpto assets.
AIRDROP
Here you'll receive Airdrop of 10 Atomic Wallet Coin (AWC) for entering your email them extra 5 for entering referral code (my code: 16YSSX). Go refer and earn even more and then stake them for 20% rewards per annum.
Note: To be able to receive airdrop you must enter your email and invite code under airdrop section and have atleast $10 worth of any popular cryptocurrency (like BTC, ETH) or else you won't receive the airdrop.

I would like to conclude this article with some feature requests
- DEX like in Trust Wallet
- AWC price change is not showing, there is always 0% change. Don't know if I'm the only one, I use atomic wallet in an Android smartphone. Where as I have no trouble with Trust Wallet it is showing the price change without issues.
