My parents thought that bitcoins that cannot be seen or touched cannot be an asset. They think that investing in physical assets such as gold, bank deposits, land etc. is more profitable than Bitcoin. But even after I convinced them, they are not ready to invest in Bitcoin. They don't want to believe in virtual currency.
It is not essential to convince them to accept their point of view resulting from their lack of knowledge and belief in Bitcoin and virtual assets. Their responses are natural since many older adults believe in only tangible and visible things, which they think are the most profitable. They need a lot of time to get to know Bitcoin, understand its investment well, and learn how much profit Bitcoin can achieve and how much it has achieved since previous years. Therefore, since you are involved in the field of crypto and are aware and believe in the future of Bitcoin, you can rely on your personal decision to invest part of the amount that your father sends to the family in Bitcoin, as it is the best of all these investments from my point of view. The person must invest in the field where he has experience and knowledge of all the risks it carries, as each person has his own decision and vision.
