I have been observing that it is very simple to obtain all bitcoin addresses with positive balances and with daily updated balances, however with Ethereum I am finding it difficult to have access to this information.

Is there a way to extract the ETH addresses with a positive balance in a simple way? Any platform or someone who sells this information? I need it in .tsv file. Blockchair doesn't have that.

There are thousands of bitcoins in the hands of the FBI, how they securely store bitcoin?

At the current price it's worth more than 7 billion dollars!!  

If the FBI wallet with 141,000 bitcoins was stolen what do you think would happen with the bitcoin price?
