thanks for the data.  I don't like the sound of USDT.  Maybe I should deal with another exchange such as Poloniex.  I would want to be able to sell my Bitcoin and end up with US dollars in the transaction.  Is there any exchange that would transact to US dollars?

What is a 330 satoshi/byte?

Regarding starting small...I could wait until BTC goes up, sell it and then wait for it to go down and buy a smaller amount
