Don't get distracted by short term price speculation. The most important metric is volatility.
You'll see a direct correlation between volatility and adoption. The lower the volatility the further along we are on the adoption curve.
Sensible reply. How can we say a market is matured when it's fluctuating at least 2-3% daily! I am still waiting for a day when Bitcoin is divided among such a large holders that news and FUDs couldn't break it more than 5% in one go. Until then Crypto market is still very prone to uncertainties and can break or rise unexpectedly. We need a lot more adoption plus stable price to consider Crypto Market as a matured one.
