No, it is not late. The markets are still young and volatile. Now is a good time to buy in if you haven't already, it's certainly much better for a newcomer now than the insane prices we had at the start of 2018. I would say the chances of another 80-90% fall from current positions are very slim indeed. A lot of us are expecting price rises during 2019. Maybe not to ATH values, but certainly x2 or x3 on current price levels.
Right, there is no word late in investment including crypto, the opportunity to get big profits in the future is very open, the important thing to do is to take decisions and risks so that we have the chance to get big profits someday.
