What you are suggesting and saying is the safest thing to do and in this way my bitcoins won't increase and only risk is bitcoin loosing value over time. I am up for little risk because Warren Buffet says - "If you don't find a way to make money while you sleep, you will work until you die". I think he is talking about passive income here and that's what i want to achieve in the long hall.
If there was a viable and safe option for passive income/increaases in cryptoland everyone would be doing it. It would be swamped instantly. The fact that it's effectively not possible is what all the scammers and assholes prey on.
In my experience people don't want advice, they just want the choice they've already settled on to be affirmed by others. I can only offer my own observations and experiences of several obsessive years observing it all and they're listed in that post. If you have that much you must've been around for a decent time too and seen the endless parade of disaster.
If you want to experiment then do so. Don't do it with anything more than you're happy to see go up in smoke.
60 BTC? Thats already the investment. Do you think you can find a better investment? 
The above. At least some of the time Bitcoin itself is doing exactly what you're looking for, it's making you money while you do nothing. You don't have to trust anyone else. You don't have to put much work in. You don't have to wait and hope that something emerges from obscurity or comes back from the dead.
