Do not listen to anyone, it is never too late to join the cryptocurrency. Just for investment you will need more money and more time to get to the bottom of it.
In fact, I think it is quite a good time now for new investors to invest into crypto-currencies trading if they are truly interested in it, since the whole crypto-currencies trading market is experiencing a bear market at the moment, new investors could get to purchase bitcoin and altcoins at a good rate, but investors should still invest with only the amount of money they can afford to lose as it is always unpredictable and risky whenever it comes to trading.
