Mobile or desktop: where should your wallet live?
The trade is not really convenience versus security — it is which attacks each device is exposed to. A practical comparison.
Phones and computers fail differently, and that is the useful way to compare them rather than arguing about which is safer in the abstract.
What a phone does well
Apps are sandboxed from each other, so one bad app cannot read another's data the way a desktop program often can. App stores review submissions, imperfectly but not uselessly.
You also carry it, which means QR scanning instead of retyping addresses — and a QR code cannot drop a character.
What a phone does badly
It gets lost and stolen, and it is the device SIM-swap attacks target when a phone number is tied to account recovery.
The small screen makes a long address harder to verify properly, which is precisely what address-poisoning attacks rely on.
What a desktop does well and badly
A big screen makes verification genuinely easier, and it is the better place to check a long address carefully before a large transfer.
Against that, desktop malware has historically had far broader reach: keyloggers, clipboard hijackers and browser extensions with permission to read every page. A browser extension wallet is only as safe as every other extension you have installed.
A reasonable setup
Use the phone for everyday amounts, because the sandboxing and QR scanning genuinely help and the exposure is capped by the balance.
Verify large transfers on the bigger screen, where you can actually read the whole address.
Keep anything you are not actively using off both, on hardware. The device question matters much less once the amount at stake on either device is small.
BYCRYPTO works the same on both — it is the same account whether you use the Android app, the home-screen install or a browser.
