I am surprised people ask for people to convince them to buy BTC. NEVER let other people decide about what you should do, if you are not feeling safe with doing it, dont. You are just finding a way to be able to blame others when things go wrong.
But do you think that you will be blamed if you are convincing other people to have some decent profit if they will be able to get some good opportunities with bitcoin? Sometimes it is not bad to be selfish and that's why we are encouraging other people to know, learn and believe what is bitcoin. Because we have proof that it is real opportunity.
I think everyone should make their own decisions. If I recommend a friend to buy Bitcoin today, and tomorrow the price will fall, one will be unhappy.
