Itu bahaya juga kalau dipakai saat ini, karena semenjak electrum
3.0+, windows xp tidak compitible apa lagi kalau dipakaikan electrum versi yang sekarang.
Ya pastinya tidak aman, apalagi menggunakan OS lama + Electrum versi 3.3.4 kebawah, dan sekarang sangat tidak lagi direkomendasikan digunakan. Selain itu, sebenarnya developer Electrum (
ThomasV) dari sejak lama tidak begitu merekomendasikan untuk menggunakan Electrum portabel mengingat kemungkinan kalau portabel akan dengan mudah colok sana-sini di PC yang berbeda
(insecure computer) yang justru malah rentan terkait sistem pengamanannya.
Electrum portabel resmi yang ada sekarang lebih ke untuk meminimalisir user menggunakan Electrum portabel tidak resmi yang dibuat pihak ketiga yang justru malah bisa berbahaya.

It is not safe to use a portable version of Electrum on an insecure computer!
Don't get me wrong: I am not saying that a portable build is by itself more dangerous than a non-portable version.
However, a portable version does not bring anything more in terms of security. It does not protect you from the computer you are using.
In addition, portable builds encourage dangerous behaviour, because they make it very easy to use your wallet on third party computers, that might be infected with viruses and keyloggers.
I was never enthusiastic about distributing portable versions of Electrum.
I did it because the demand for portable versions was so high that portable builds distributed by third parties were getting popular.
That's the only reason why I accepted to distribute portable builds: I do this in order to avoid an even worse situation.
