Inviting them to buy, of course, is a risky thing, although the opportunity for profit when buying at the current price is very large but the risk is always there, even many analysts are sure that prices can go down below $ 17K.
This is why its really important that you should really make explanation about that particular risk into your friend because even us who are been here on this market for a while does know its potential in
terms or recovery but into those people who do just recently know it whether because you do introduce it to them or get it on other sources then it would be normal that their hopes are really that high which they do even believe that on the time that they had able to buy then they do expect something gains after than which its not always the case.
You can recommend but never ever make out assurances about making profits or money.
