Recommendations of any investment assets are always risky, especially when dealing with family members. This risk is amplified with cryptocurrencies, considering that the majority of people don't understand that you can easily lose 80% of the value within a single bear market. And guess who gets the blame?
Totally agree with you!!And in the world of business, the code says don't mix business with friends and family because this is usually your weak point and you wouldn't have a clear mind to make a sound decision and worse off giving parents
financial advice where they need to take their moñey, comeon 
Bitcoin investments are usually long term if you are a hodler and I think parents are the wrong target market, instead invest for the younger generation day your kids, younger nephews & niece's or yourself as the profits will be enjoyed in the future when price and Bitcoin demand grows.
