No. It is not too late because there are many people who uses bitcoin who wanted also to invest but they have a question in their mind if it's too late. It's not yet too late because as long as bitcoin never stops, investment will never stop also. As long as there are users, there is bitcoin and if there's bitcoin, there will be an investment.
Yeah I agree! Ofcourse it is not too late to invest in bitcoin. As long as it is still in the run and still kicking, investing in here will not be too late to try. No matter how late you are to be an investor of it it will be worth it in the end because the current situation of it is good although it faces challenges. The user of bitcoin is increasing that may lead to the rising of demand in the market. So don't be afraid or hesitate to invest.
