To my hypothesis, there are a lot of crypto enthusiasts who are fond of keeping their private keys, Keystore / JSON File, seed words, mnemonic phrases etc to their wallet on cloud storage platforms like google drive and the several others. From my little research and experience, I personally think to keep these sensitive data isn't the best due to its nature of proneness to unauthorized accesses.
I'm positive there are individuals in this forum with profound knowledge regarding this topic. We would be grateful if you share with us your experience, tips, advice and most importantly, secured ways and means we can manage our private keys.
Thank You!
For me, you just have to secure your computer if you really put all of your KEYS or anything important to any of those software. But I really like keeping those in a piece of paper.
