Are you an altcoin trader? Bitcoin dominance is the most important metric you should monitor.

In theory as technology improves there will be more use-cases of cryptography & blockchain. The higher number of use-cases suggests $BTCD should keep going down over time as alt tokens market cap rises. The market has a tendency to overvalue projects & push price much higher due to strong +ve sentiments of market participants during the periods of strong rallies.

$BTCD over time has held support near 37-42% range, this should be a primary profit taking zone for traders. Keep an eye in this level.
