Got laughed at when I suggested using crypto to move money between countries

So my parents have two appartments that they want to sell in my home country and naturally they want to transfer the money to our current country.

Our home country has a different currency than Euro and they were talking about how you need to have an account in Euro in the first country or they'd have to pay a big percentage in fees and it was really not viable without such account.

I already knew my mom was not a big fan of crypto as mentioned in another post that I made a while ago, but I decided to make the suggestion anyway because she may finally understand the benefits.

Nope, as soon as I suggested a stablecoin like Tether or USDC she thought I was joking and immediately discarded my suggestion as if I was making fun of her.

Not to mention crypto is not even regulated in my current country (Portugal).

At least I tried. ????‍♂️
