I agree with this one hundred percent, no one knows that coin or token that will make one a millionaire....

After all said, i concur that there is no late comer in crypto, as long as New projects/coins are being launched everyday in their tens and hundreds.
But am still of the opinion that the earlier one gets involved, the better, you have more opportunities and chances of succeeding than those joining late.
To illustrate, I doubt you will find anyone who's been involved in crypto since 2009 who haven't made it in millions today, if there be any, they would be very very few of them which be due to one or two mistakes they made.

As a conclusion, it's heart lifting to know that no time is late to join crypto, but again, I retreat that the earlier one starts investing in crypto, the better for such person.
