    My understanding of block chain from watching this video tells me that it's a ledger of transparency that allows trading partners to verify the legitimacy of a supposed payment attempt but does nothing else really. A bank tranfer denial may not be instantly recorded but anyone sending more than what they actually have fails both in the banking system and the block chain system. The block chain allows traders to view partners current bitcoin balance but fraud happens from interpersonal promises anyways. The failed bank transfer can be from other non trader based origin and so a block chain doesnt do anything to legitimise an earnest traders promise of future bitcoin purchases when their purchase or exchamge can still be denied by the bank they use anyways. What ive seemed to have learned is that the block chain is a mode of transparency for guaranteed exchanges but accounts for nothing regarding borrowing, loans, installments and other non digital and frankly human based trade options and agreements. I think the block chain is a basic cloak for a greater fraud. Yes you cut out the middle man, ie banks and their surcharges and penalties. But you expose yourself to liars and unvetted characters too. Overall, i recommended buying bitcoin as the firmly established digital currency rather then betting on random upstarts with high risk nature. With your bitcoin balance make purchases you benifit most in terms of its security value. For example, shopping deliveries to your home neednt be in bitcoin. But specific online investments are safer with your digital currency because of its digitally tracked and recorded ledger status. Am i right or wrong?
