My persona cut-off for BTC/USD is 16.5k. If it goes above it, I would take that as a trend reversal.
I am more focused on IOTA and Streamr/DATAA at this time. I have high hopes for both of them.
Also Coinbase should open OTC BCH trading soon, which should raise the price. Others such as GNT, QTUM, QASH, and SNT should be monitored closely.
