I don't know, how you see it.
Explaining Bitcoin to parents is very challenging and difficult, because there are more than 4000 different cryptocurrencies circulating on the market. Of course, when explaining bitcoin we will also explain altcoins and this will make those listening dizzy. So we have to explain slowly and the purpose of creating bitcoin in detail so that in the end many people have been able to gain profits from investing in cryptocurrency.
Therefore, there is no need to rush to explain it. Even if he already understands, we don't need to impose our will on his decision. So your mother made a good decision not to invest immediately after you explained. Instead, he researched it himself so that in the end your mother wanted to invest in bitcoin. In essence, to make it easier to explain the use of investing in bitcoin, it is an investment for the long term because bitcoin is better than gold. There is money, don't just save it, but rotate it either for business or future investment, because if the money is just left in the bank it won't produce anything while economic inflation is getting higher.
