Till the time speculators gamblers big whales are interested in doing business here believe me you are never  late.  Because these speculators will never allow the market to remain stagnant. The will always be busy in push and pull of bitcoin.
Now it depends on your intelligence when you enter the market.  At push or pull?  Means bullish or bearish market.  Also i want to add that till date very high percentage  of population still not heard bitcoin.  So you are also early as compared to those non entrants.
