monero going down with majority of alts. btc has been sideways for quite sometime.
do you guys think this is the start of a dump?
No way! Tiny fluctuations in short time periods won't give you a good picture of the overall trend. Pull your perspective back a click or two, and give it a little time.

Up, up, and still going up! Looking back, that "dump" on 12/14 barely registers on Monero's trajectory.
