If the bitcoin value keeps rising over the coming months to up to and over $20.00 a coin then each BTC0.0005 transfer fee would equal $0.01 and above.  Talking about bitcoin having free or very low transfer fees wouldn't it be best to move the decimal place and make a bitcoin instead of worth $20.00 a coin but to $2.00 a coin keep the transfer fee BTC0.0005 and have 210,000,000 coins in total instead of 21,000,000 coins.
