"No Man's Sky" probably has around 18 quintillion possible planets that are all unique and while chartering those new places, you will need to earn units. Players must have the best ships and equipment to be able to enjoy what "No Man's Sky" is offering.
Nearly 24 hours after "No Man's Sky" release and players are lost. The vastness of space and chartering new territories for the first time that no one has ever seen yet is mostly high. To be able to concentrate first on areas where units can be earned, players have worlds that are rich in resources.
Once you find planets such as these, you will be able to do custom-mining which you could resell and get your earnings. However, you also need to watch out for thieves. There are instances, where other lone ships may attack you and claim your cargo as they are also looking for minerals to sell.
You could also become a thief yourself by attacking other ships but this behavior may not do you good in "No Man's Sky" and others may also attack you if you are not careful. Also, this behavior could lower your standing to other players, which is by no means good.
Another way to earn precious minerals is by searching for chest icons. In "No Man's Sky," players may be able to find a gray treasure-chest icon that can be claimed.
Once you are in the role to getting more units, it is time to upgrade your Exosuit with the use of Drop Pods. This will allow you to carry more gathered materials. Upgrading your Exosuit in "No Man's Sky" will allow you to carry more resources, which in turn more money for you.
To find the Drop Pods, use the Signal Scanners. According to IGN, use the Bypass Chips and search for Shelters to be able to find the Drop Pods where you can finally upgrade your Exosuit.
And to be able to earn money in "No Man's Sky," you need to spend money. Make sure to buy more slots for your ships so that you can carry more. The more your buy for upgrades, the more that you can earn.
