Recommending someone to invest in Bitcoin is some how risky. If the don't have the patience to wait for the bull season to commence the might sell at a loss and but the blame on the introducer. And many likes attributing their failures to someone then their success to their personal effort. I have learnt from past experience that before I recommend Bitcoin to a newbie I will first ask how long the can hold for and that will determine if I will be willing to proceed with guidance or end it there.
It's not all about how long they will hold, it's how knowledgeable they are about of what they are dealing with. It's easy to invest into something but hard to get the profit/ROI that you want. So, if a newbie would want to invest this might take some personal or shared experience before they decide what to do with their investment.
If they have a good mentor then they are lucky to have one compared to those who are self-learning because it might take some time before they learn their lesson.
