You need to convince yourself about an investment and not let others do the thinking for you. Some are into bitcoin for financial freedom without depending on the banking system, some buy it for the potential ROI, some others use it as a retirement plan, the purpose is different for different people.
Understand what bitcoin is and what value it offers, then decide to buy or not.

I second this. The decision to make that investment and risk your money on the line isn't for your friend to make or whatever acquaintance or relative you have. That solely lies upon you cause at the end of the day, it's your own moolah you'll be putting down and would be risking, you can't have scapegoats when shit hits the fan and you lose it all. Whatever the reason for investing really, it has to become something that came from your own volition.
In that regard, I suggest that OP look into a couple of revered articles and researches about bitcoin, maybe even give the whitepaper itself a quick-read since Satoshi Nakamoto made it understandable to even the dumbest form of dimwits on the internet. Look it up, research, and then from there decide whether you should invest in it, or bitcoin's not for you. Don't put in money just cause "a friend told me I'm gonna be rich with this".
