Its not too late to get involved in bitcoin. Yes, there are plenty of people become wealthy by the help of bitcoin, and we are reaching the bitcoin limitation. But its not too late if you are gaining bitcoins right now its because know that you are starting to earn some money. Maybe, there are only 20% of peoples population that are using bitcoin.
if indeed you intend to really follow bitcoin, to my knowledge also is not too late in a journey.
it's just that you missed out with other friends who have built the account too long enough.
so at this time there is no word late, whatever your business in managing bitcoin then it should remain grateful.
It is definitely not too late. The journey is just starting actually. If you check coinmarketcap website Top Gainers list you will see that every day a lot of coins are making at least 5X so it is clearly not late.
