I started off Bitcoin years ago, my family never believed it and said it was all a scam and I should stop (of course I didn't), when Bitcoin was making progress over the years, the influence on people starts to get stronger as time goes by, more and more are starting to believe that there is a thing called "Cryptocurrency".
You are not alone, I'm sure many Bitcoin enthusiast also has a hard time with people around them. But the good thing is that you didn't change your mind and still pursue your choice of getting in the Bitcoin bandwagon years ago. There are a lot of non-believers up to this day, but it doesn't matter.
From telling me to not do Bitcoin because I'm just wasting time to "son, can you teach me your knowledge about Bitcoin?", this is where I realized that Bitcoin is definitely the future to be, to see is to believe and they started to believe me, they did because they saw the value going higher and higher each year, 2020 was the year Bitcoin's value exploded to $20,000 and this was the year that they are convinced that Bitcoin is real, they were so down thinking that it's too late for them, but it really isn't and they can definitely keep up, I hope your family is convinced as well that Bitcoin is real by now and not a joke, I've opened their minds and I hope you can open your friends, or the people that matter to you, because it can definitely help them.
You don't have to wait or rub it in, definitely there will be a time that your family will realized that you make the right decision in your life. If they are still interested then good, but if not then continue what you are doing and don't be affected by the negative thoughts around you.
