The thing is, once you’re at that point, you find yourself wanting to share this excitement or knowledge with those closest to you, not to inflate the value of your holdings (unless you’re a cousin of an Arab sheikh, they’re not going to move the price), but because you truly believe in its transformative power for their financial future (they will remember you in the midst of a bull market, but it won’t be the right time either).
You need to find a way to simplify the meaning you want to convey to parents and if your intention is to provide them with an understanding of Bitcoin then it must be done in a much more binding way. You also have to know the character of your parents and if they are a little unfamiliar with the investment route then what you want to convey will be much more difficult for them to accept. You should also understand their previous work patterns because not everyone will be interested in investing, especially involvement in bitcoin.
If your parents are unfamiliar with technology then they should not be involved in investing. You can ask for funding and manage the investment yourself because if you give them access, it doesn't necessarily mean they can do it. I think you know the character of your parents at home better and you also know what to do when your parents are not close to investment patterns.
