Charts look Almost Identical Today

I'm looking at the charts today on coinmarketcap.com and something about charts stands out to me. Take a look at the charts and tell me if you can see anything?

Seems to me that you could invest in an altcoin that cost less than Bitcoin and still get the same movement since most crytos follow BTC anyway. Looking at the charts here though it's surprising how closely correlated they actually are.

You can also see that BT as well several others have a slipped lower today as BTC creeps closer to that $10,000 support line that has been holding it up. Maybe the new price will spur additional buyers to get into the market to take advantage of the entry opportunity.
