this is normal i think we cant receive an increase always their will be a time for decreasing also but this decreasing will be a big impact to the price of bitcoin later. because last year bitcoin pumps so high thats why this year will be more pumps for bitcoin.
Obviously the market price should not always increase because people will not gain profit if the market price is just continuously increasing and that is the reason why cryptocurrency is profitable its due to the volatility of the market.
