Try to see the current price, it has a very cheap price and this is a very good time to invest, and I think you are never late
Yes, It's never too late or too early because the crypto market always fluctuates, like ebb and flow, so whenever we joined we should be happy that we could, minimize our risks and maximize our profits.
It was the best strategy at 2018 instead of simple hold at 2017. I think today is not bad time to invest. So cheap price can lead to good profit in future.
