your better off using other alternatives as buying with debit card normally means you will be charged more and a lot of the biggger and safer exchanges dont accept debit cards

Is this possible? If this did happen what would the attacker have hold of? I don't they would have your private keys because you sign the locally but I may be wrong please let me know if I am. If the servers got compromised no one would be able to send transactions right?

this is the one problem I have with multibit you have to rely on them.

Well no alt coin is near 100 dollars yet? so how come you claim bitcoin has died even though its worth god knows how much if you combined most alt coins together?

No one should buy this as the seller would always have access to your bitcoin as long as he keeps the private key.

No there are many online wallets but blockchain.info is the only trusted one and the longest running.....online wallets can be found inside coinbase too which is used by many just for hot wallets and not actually trading.
