Hi, all:

I develop a bitcoin trading platform, that include one online wallet.

I think that all users be able to withdraw cash in any time, so I don't use
any offline wallet. I call my online wallet is "pure hot wallet" :-)

I will set password in online wallet, only I know the password, and will
create 100000+ users, every user will have at least one transaction of
recharge bitcoin and withdraw cash.

I have two question now:
1. If nobody can get file "wallet.dat", does my wallet is security?
2. If somebody can get the file wallet.dat, does he or she can get all the bitcoin?

Thank you.

Hi all,

I develop a bitcoin trading platform now. I use the version 0.9.4 source code and want to sync all block data, but seems have some error in file "~/.bitcoin/debug.log":
