To you the current market situation seems like a normal situation to invest but honestly to me every situation in Bitcoin seems good enough to invest. But we can't predict from which stage the Bitcoin market will go. Just as Bitcoin can move from lows to lows, Bitcoin prices can go from highs to highs. We cannot say anything about the Bitcoin market in advance but by researching the market and observing the market regularly, one can predict the market movement to some extent. 
Investing in Bitcoin and holding it deep is a very challenging thing for every investor but those who accept this challenge and hold their investment deep achieve success. 

Ever since my childhood, I have heard a saying from my mentors that if you are patient and focus fully on your goals then you are sure to succeed. I believe this saying and I think it applies to all cases. Like us it takes years to complete a particular course be it your medical course or engineering course. Completing these courses must take a certain amount of time, a student has to put in a lot of hard work, be patient and focus a lot only then he can complete these courses. If a student cannot withstand these pressures and focus on studies, he/she drops out prematurely and cannot achieve success there.

Investing and holding it deeply I think is like completing a certain course in real life. Just as the course is not complete if the education is left before a certain time, if we cannot hold the investment for a certain time, the investment remains incomplete, so we must have a tendency to hold it.
