This is something that I must need to consider because I have some big number of addys in my wallet there and most addys are having payments received from faucets. As the value of bitcoin is too low, I never thought about moving them but I have back up of all my private-keys. As I "own" my bitcoins, I was thinking like I am not having any problem but now I realize I may go wrong if they are somehow able to access my privatekeys.

(Just 2 weeks back, I checked my wallet using their recovery link (https://login.blockchain.com/wallet/forgot-password) and got busy with my routine works. It is really hard life from my end. You guys believe or not, I have not claimed BCH for my bitcoins yet (Now, it has turned as BCHABC and SV)).

Definitely there could be hundreds of us. But, some may have privatekeys but most others might not have taken bitcoins serious then and after seeing bitcoins around $10k may think about digging and ending up clueless. Bitcoin must be treated seriously so that you will learn every safety measurements to protect it. Otherwise losing them due to unable to access or ending got hacked might be a result.
