I think it is never too late to invest in the future, as crypto IS the future 
It is always good to invest some of your income, maybe just 10%, and be patient. But it is best not to invest more than you can afford to lose guys.
Your strategy will work over the long term but many people simply do not have the patience to invest just to per month in this market and wait for years in order to see their profits, and I'm really happy about it because if the people were really patient and saved their money and invested in this market then I'll be unable to get the profits that I will get in the future thanks to them.It is always good to invest some of your income, maybe just 10%, and be patient.
