I still think that this is the best way and I am doing it for myself and hopefully for my future children as well. I believe that if you could have even just one bitcoin, in 20-30 years you will be able to retire easily, that's all you need to reach. And yes I know that you are not going to get one bitcoin easily, that's a lot of money right now, but imagine how many people in the world save up enough for one bitcoin and do not invest into one bitcoin, that's my point. A lot of elderly people have enough for one bitcoin and do not buy it, a lot of even young people save that much from somewhere but invest into golds or stock or even gamble.
