I feel its the same case with everybody. Even I have met some people who wants to make investments and earn high returns but don't have that much of a risk taking capability.
That is why I mostly advice people to invest according to their risk appetite as mentioned in my previous post.
But not everyone falls in the same category and there are people like us who prefer holding bitcoin for long term to reap it's long term benefits.
We can only suggest people the best thing to do and leave the rest upon them but do not "guarantee" anything and always let them know the potential risks and cautions of investing to stay on the safer side.
Not everyone are happy or sustain in high risk or competitive thing, hence many people are end up become mediocre because they don't want to go out from their comfort zone. Investing in Bitcoin for the first time is hard because they need to control their mental and emotion.
It's also depend on how much they willing to invest, they might be fine to invest 5% of their wealth in Bitcoin, but as we know 5% in Bitcoin, but they hold 95% in cash, the profit they will earn will not be much.
