When it comes to investing no ones too old or too young to invest. But you must still have at least enough knowledge and funds to be able to invest and trade in cryptos. Ever since technology evolved even older generations are slowly becoming tech savy. Since they also need to cope up with the changes instead of depending to someone to work it out for them. Like in japan where old people rather try something out themselves than to depend too much on someone to do it for them. Same goes when they do trades.
