$BTTC's smallest possible price move is one tick, and at today's price that tick is 2.8%. So its entire 24-hour change — 0.00000037 down to 0.00000036 — is exactly one of them. $ETH fell 7.8% over the same window, with a tick worth 0.0004%.

At 02:19 UTC the bid and ask were one tick apart too, so crossing that spread cost about as much as BTTC's whole day.
