1. First of all, Bitcoin is not a replacement for gold by any means, it is something totally new.
YES, IT replacement.
2. We had spam attack every day in the past
IT NOT SPAM, JUST TO MANY PEOPLE WANT MAKE TRANSACTIONS, WHO DONT WANT PAY FEE - REJECTED, COSE NO FREE SPACE IN BLOCK
3. I've read this text and I have mixed feeling, for example - author said that: "GOLD EXACTLY SAME A PYRAMID SCHEME AS A BITCOIN BUT ALREADY ABSORB ALL IN"
If he thinks that gold is a pyramid scheme then I have no more questions. We are simply not on the same page here.
GOLD MOST USED ONLY FOR MAKE RINGS, IF ALL GOLD HOLDERS SELL GOLD TO RING MAKERS PRICE WILL FALL TRAGICALY
ALSO NOW MORE RARE AND BETTER IRIDIUM COST LESS THAN GOLD, POSIBLE TO MAKE FAKE GOLD WITH GOLD+IRIDIUM+SILVER
