That's kind of how most of my inlaws are. They were gifted some BTC and they are just holding it waiting to sell it. They don't really care about it, they don't care how it works, they just are waiting for me to tell them when to sell it. I think most of them are cool with a 10x, so if it hits 170K ever, then I will have to figure out how I am going to get them out of it!
If it hit 170 for sure - but if they have 1700 worth now, would they be as happy? The thing is with the smaller amounts for many people, is that once it is up, they will wish they put in some more.
They have pretty much forgotten about it. Every now and then they will say, hey, how is our BTC doing. I usually say "your BTC is worth $20 more than it was, my BTC is worth much more because I bought much more!".
