Today I open Bitcoin Core 10.2 and it takes a long time, then says ERROR, and crashed.
I open again.  Blockchain data fucked, must redownload everything.
Error?  How?  Did blockchain.info rewrite the blockchain logs to backdate and steal?  HOW?

Because I go to blockchain.info to check my only known account, sometimes I use blockchain.info only to look at my account balance by searching my BTC receiving address.  Is this address a secret??

Suddenly my account is $0.00!!!!!!!
It says all my money was sent to another account on 2015-07-18!!
Then another, then another, then another... etc  and then parked at a new wallet that is unknown to me.

HOW?  How could I be broke on the 18th, when I made transactions on the 20th and 22nd?
My money was still mine and I was still using it to buy stuff on purse.io on the 20th and 22nd.
According to Blockchain.info I have been at ZERO since the 18th!!

Now my transactions say "conflicted", but my blockchain is not finished downloading and will not be for many days.

I spent the money on Purse, received the goods, and paid.

Did someone rewire the logs to make it say I went broke on the 18th and just make the 20th and 22nd transactions conflict?
WTF is going on?
Or does the blockchain just randomly reassign me new wallet addresses and I will see this after the blockchain updates?
How the fuck?
And why the heck does it need to redownload the blockchain when it still has 46.8GB of blocks?
This is stupid that the BTC Core crashes so easy then requires a full re-download!  Seriously?
Whose dumb idea was that?

I am freaking out because blockchain.info has ALWAYS shown my balance just fine, until now.
