Most people should install the latest version. But if your phone is older, or a new update broke something on your device, you may be looking for an earlier release. This page lists every Bitunix Pro version we could verify, from 3.32.0 to the current 4.1.0, with release dates, sizes and what changed, plus the honest safety warning that comes with running old software on a financial app.
For most readers, the answer is: nobody. The latest version has the newest features, the latest bug fixes and, most importantly, the latest security fixes. But there are two situations where an older build genuinely makes sense:
The warning that goes with that: every version you skip is a set of security fixes you do not have. On a normal app that is an annoyance. On an exchange app that holds your funds, it is a real risk. Treat an old version as a temporary fix, not a permanent setup. Keep two-factor authentication on, use a strong password you use nowhere else, and move back to the latest version as soon as your device allows it.
From the current 4.1.0 back to 3.32.0. Where a date or size is marked "Not listed", it means we could not verify it, so we left it blank rather than guessing.

How to read this table: the 4.x releases are the current generation of the app. Everything from 3.54.0 down is an older build. If your only reason for wanting an old version is curiosity, do not bother. If your device forces the choice, pick the newest version your phone can actually run, not the oldest one you can find.
Here is the part most APK archive sites will not tell you: the official Bitunix download page only distributes the latest version. There is no official archive of old APKs. That means every old version you find online comes from a third-party mirror, and for a financial app that is a genuine risk. A modified APK can steal your login details or redirect your withdrawals, and you would have no way to tell from looking at it.
So the rules are simple:
Not from any official source. Bitunix only distributes the latest version on its official download page, so old versions exist only on third-party mirrors. That is exactly why they carry extra risk: nobody at Bitunix has checked the file you would be installing.
Less safe than the latest version, for two reasons. First, it misses every security fix released since that version. Second, a file from a mirror site could have been modified. If you have no other option, verify the source as far as you can, scan with Play Protect, keep two-factor authentication on, and move back to the latest version as soon as possible.
Almost always one of two reasons: your phone is too old to run the current build, or a new update breaks something on your device. If neither applies to you, install the latest version and ignore the archive.
On Android, go to Settings, then Apps, then Bitunix Pro, and the version number is shown on the app info screen. Compare it with the current version, 4.1.0. If yours is older, update from the official download page. Our update guide walks through the steps.
Unless your device forces you onto an old build, the latest version is the safer choice. Get it from the official source.
