You don't have to confuse your parents that Bitcoin is the best investment than gold and land, remember, the money isn't even yours, you strongly believe in Bitcoin and they strongly believe in gold and lands, why not save up some money for yourself and invest in Bitcoin? It's only a matter of time to proving them wrong that Bitcoin is the best overall.
When parents failed to understand, the only way to prove them wrong is results, and find a way to get some funds, learn about how to keep your Bitcoin safe for long term too, you don't want to lost your Bitcoin later on, they will tell you they saw it coming, when the time is right they will be surprised.
When I started getting some Bitcoin I kept it as a secret because I thought my parent will never approved to it, and I was right because later they knew, but I ended up taking responsibility for my parents using Bitcoin money and that changes everything between us, they showed support after I proved them wrong.
When you are trying out to convince your parents on allocating some budget when it comes to Bitcoin investment then tell them about the basics.Dont explain out with too much technical stuff so that they would really be able to understand. Its not shocking that they would really be refusing at first considering on tons of scam investment that we do have on line on which most older people would really be having that kind of mindset that it is really just that some another sort of scam on which it is really that hard for them to get convinced on what you are trying out to deliver. If they have decided on not to invest then better not to force them on,
but rather you would really be just that finding yourself on the way for you to invest alone.
Yes, its hard but its not something impossible on which if there's interest then there's a way. It is really just that a challenging thing on trying out to explain something
into your loved ones but turns out that they didnt listen because they arent get used to it or havent been able to heard it out about it.
So it would really be that just on personal choice whether you should pursue on the things that you are trying to achieve or not.
