As BTC approaches 15.5k-16k zone we could see a strong bounce (see horizontal support and ascending triangle).
If that happens you'll want to be moving some of those alt positions back onto the BTC train.
Interestingly enough Market Open (11am Sydney time) Friday is traditionally the worst time of the week for BTC, but that might be about to change. As a side if it does have a big dip at 11am, 2pm might not be a bad time to buy in, check TA and DYOR because it's all guess work atm.
