To answer your question, I will tell you something that good to try.
Last year, my friend tell me he buy 3 btc when the price is worth $700. He said he just want to save his money in another place, not bank. So bitcoin is one of any choice to save money. But what happen now with the price? Now, bitcoin worth to $1200+ and his money is grow. It is same like investing money in the stock.
Your friend did a great job of speculating the right price of bitcoin, and that's what you get if you believe in the future of bitcoin, people who have patience to hold and buy in the past are now enjoying a great profit. I hope you were influence by your friend too so you both are enjoying now.
Honestly, it's easy to say stuff like that after the event and now that we see it's a profit, but the real challenge for us is to decide to buy in the actual situation.
