I've done a lot with my friends for telling them to invest in Bitcoin and they've seen the results on me. But even with that proof, I don't think that investing in Bitcoin is for everyone. People likes to see results and want it to happen on them if it's positive and yet, they don't like to go through such tough times thinking that it becomes a scam when the price goes down and they'll blame the person that has discouraged them to invest. That's why it's no longer of my concern to tell my friends and relatives to invest in it, let them do all of the research and see for themselves if they're one of the fittest people to invest in it.
BTC is for everyone but some chose not to invest their money on BTC their government don't have power to control the price in the market. Like the ones that have knowledge of BTC, they will not wait for people to force them to invest in BTC ot trade BTC because they have read and learn what they want to learn to have the knowledge that is helping people to make progress in BTC investment. But if you don't have the strength of hodling BTC for long years I will not encourage you to start with big amount of money on BTC trading, because any money you lose now it will not come back to you at the moment.
I don't stress myself these days to tell people to invest in BTC or involve in BTC trading, because some of them have heard about BTC trading but they don't believe it will favour them in the future or when trading base on what they heard or know that BTC is not control by the government.
