yep paper money is worthless,its basically an i owe you,look on the note,it says i promise to pay the bearer the sum of.think if you had 150,000 pounds in the bank and we switched to the euro overnight or the pound crashed,your 150,000 bits of paper would be worth sweet FA.banks are not safe as weve all seen.the only safe way is commodities like gold,silver,lead,copper as other countries are buying it all up,and this is a resource that WILL run out one day,so it will always be tradeable as a currency (like in the old days) and is 100 per cent gayranteed to rise,...one day because they arent sustainable products.buy it here and there when you can and bank it in a safe,bolted to the floor under your bed for a rainy day,at least thats what im going to do
