- Send them affordable Bitcoin on their birthday.
Give them bitcoin as a gift, but not on birthdays and valentines days and Christmas and stuff. A gift(especially for these special days I've mentioned) are mostly something to make them happy; not an opportunity for you to shove down your interests to them regardless if you have good intentions.
If I get a gift like this, I'll definitely show it off in front of my friends because I'll be very excited, I know the price has dropped a lot now, but I'm full of good imaginations about his future, I'll find a safe one Save it in my wallet, maybe when my friend and I have known each other for 30 years, I will take it out and turn it into cash for a long trip, just as a travel fund.
