Hi
is it a good idea to store bitcoins in popular online wallets like blockchain.info or coinbase
can these wallets get hacked one day ?

 is this possible ?

Hi, i believe the bitcoin will be the currency of the future
and it's a threat to the federal reserve
but they are not going to just watch their system collapse of course
how do you think the federal reserve will react ?
