All wallets should have coin send and receive function. This section is for starters who have not used cryptocurrency wallet before. If you have, you may skip this section.
Although I believe that I should never recommend anyone to only buy bitcoin and altcoins, I strongly recommend everyone to have cryptocurrency wallet. The most minimum of all to enter cryptocurrency is to have an interface to receive coins and that is a wallet. I believe that a future will come where many people will need bitcoin and altcoins and there's no safer way to get some other than having a wallet or at least a public/receiving address. In my experience, most of the people I have introduced bitcoin who did not have computer literacy background, have trouble even figuring out of how to receive coins.
The other bare minimum function is to send coins. Nowadays the age of cryptocurrency adoption have not come so the send function is not used much. If cryptocurrency becomes widely adopted one day, the knowledge of how to carefully send is necessary with current system. The transaction is irreversible, one wrong character when inputing address will result in forever coin lost. Does Atomic Wallet have these foolproof functions?
People use different operating systems so if Atomic Wallet only supports few operating systems, it will be difficult to refer. So, what does Atomic Wallet support:
Private Keys or Seed Phrases
This is a very important thing that anyone who dives into cryptocurrency must know. Basically, not your keys, not your coins. If a 3rd party holds your private keys or seed phrases means they have full control over your coins. Like the current banking system, do you trust them or not? Is Atomic Wallet a third party online bank or your own bank?
Supported Coins and Tokens
In Wallet Staking
In Wallet Exchange

About being light weight or not, I'm not sure since everything is running well on my devices and I haven't tried on lower spec devices such Raspberry Pi and old smartphones. Leave a comment if you know more and I will update this post.
