I believe that , there is no better time to start than now, if you weren't privilege to start earlier then start now . You can even make more than the people you think know it all or have it all.
Anything you do majority of it depends on determination, when you are determined to do a thing, it almost have done , so for me no time is too late to start, bro start investing now.
Those who haven't invested anything into Bitcoin till now must invest the moment they have anything spare in there pocket. It's better to invest at any point rather then staying as no coiner. At the moment Bitcoin price is 103$ and if you are looking to invest then you have the option to wait for a while for price to go down or you can still accumulate using DCA strategy. Bitcoin has this beauty of going down after every bull run, the price is 103k$ but that doesn't mean it will never go down.
