Mate. I needed this ahaha.   

Two active scammers: iPhone9 and LBCAIO to that list as well.

Also, asked to use an escrow with Nvidiafan or get him to go first and wouldn't do either. Bit concerning.

There needs to be a greater sense of price stability around Bitcoin in order for it to become a true international currency. This is made evident by people on the forums still quoting prices of goods and services in terms of USD in Bitcoin and not just in bitcoin itself.

Another issue is, as many have mentioned, Bitcoin's effective deflationary record. As the value of the currency rises, there is a greater incentive not to make any transactions for goods or services because if you wait a few days then you may have more purchasing power. This concept is consistent with any fiat currencies that have experienced the harmful effects of deflation in the past and why many central banks around the world do all they can to keep deflation from happening.
