Just do it how most people do it, the easy and straightforward way. Earn fiat through a job, a business, or a gig, then use a percentage of the earned fiat to buy bitcoin in a peer-to-peer exchange. Or better, you can try to ask your employer to pay you straight in bitcoin.
This is exactly what I didn't strive for. In order for people to spend their hard-earned fiat for crypto, they have to be very convinced that what they're buying is worth an investment. If they get some crypto for stuff they do anyway that's a much better way of introducing crypto / Bitcoin to average people.
Ok, on the top of your head, name one investment where you got 800% profit in one year? Also, Bitcoin is a high risk investment and should only
form a small part of your larger portfolio. There is no guaranteed profits in Bitcoin investments, but there are a huge potential for large profits.
Look at the price history of Bitcoin and you will several opportunities where people could buy low and sell for a massive profit. I buy/sell old cars
and I use the proceeds to buy more bitcoins.
Not sure whether this is going the right direction, but what I meant is that giving non-Bitcoin-educated people easy access to Bitcoin by "just giving" it to them is probably a better path to adopting Bitcoin than telling someone: "Hey, there's this great thing called Bitcoin which can make you money - go invest!"
That's why I was also giving examples like Lolli or Wirex - people can just shop without thinking about the price of Bitcoin (at first) or whether they're making a good investment, because they get it anyway.
Exactly the topic was going a bit off track. People will not be convinced by just saying bitcoin investment is something you must try because it gives you profit, they need to see something in order for them to believed like besides giving bitcoin to them, you can show them how you invest in bitcoin and how will you earn your profit in there, once they know how to do something they will surely be interested in it and will definitely ask you some more about bitcoin investment.
