According to this post
http://www.reddit.com/r/Bitcoin/comments/1yzbhg/bitstamps_bank_refused_to_open_me_a_bank_accountUnicredit in Slovenia (the bank Bitstamp uses) and Sillcon Valley Bank (the bank Coinbase uses) are both declining bank accounts to new bitcoin-related firms.
So for new companies in the bitcoin business it will be probably nearly impossible to get banking accounts, if even these banks which already have bitcoin related accounts (coinbase and bitstamp) refuse to open new accounts.
The probability (with the MtGox and the Silkroad scandals in mind) that these Banks are also shutting down the accounts of bitstamp and Coinbase is not low.
Then we would loose even more important exchanges, people with FIAT on these exchanges will not be able to withdraw any more.
People who are exchanging btc locally are also in danger to get imprisoned for money laundering already.
All this would be a very hard hit to bitcoin.
What do you think? I this a realistic scenario? Should we really worry?
