If you look thoroughly, then BITCOIN is just money,
It's money and also an investment vehicle.
but like money, can it improve the world around, and humanity as a whole !?
It depends on may factors. Does Japan Yen make life better? Not at all, I couldn't care less about it.
On the other hand, Bitcoin is great because if you work for it, you'll receive in your own wallet, without knowing or caring about banking days or conversion rate/fees between employer's home currency and yours; it can be kept for long time in the wallet and, if you are careful, nobody else can touch it. So it's the best money over the internet.
Also instead of being touched by inflation (government's way to steal money), it's finite supply and its price even rises greatly over time (if you have enough patience).
I don’t think “good” and “BITCOIN” are the same thing, most likely the opposite.
It can be bad too.
If you don't afford to keep it for longer, the fees you pay for the services to convert to your home currency may make it not worth the hassle.
Because of money, a person becomes weaker, he does not need to do something, to develop, because money will do it for him.
This is weak propaganda.
Go into the forest, live without money, become strong. But if you get injured, don't come and ask for help from the medical system people are paying for.
Go into the wild, live without money, become strong. But if a bad year comes (insufficient rain, or even fire, for example) and you don't find enough food, don't start begging for money...
All in all, money is a tool. You can use it wisely or not. Same goes for a knife too, for example.
