Risk in bitcoin investment is kinda low, because if you're in the category of long term holder/ investment then the risk is very low. You should go invest in bitcoin right this time and wait to see the prices goes up and don't forget to store your bitcoin private key in the safe place

I am not surprised with the price of bitcoin right now because i already know that bitcoin would come along this far. Bitcoin is still on the process of finding a good foundation or support in the market and it seems that it doesn't found one yet so what happening right now is, it is retracing to find a good support and i think that the price of bitcoin will be on the top soon.

yes it’s very very risky, BTC price can rise or fall at any time. Bitcoin market today is still very volatile, because of many new players here. if you invest your money then BTC price drop down at any time , what are you gonna do? will your hands be strong? from where money for your daily lives if you allocate all of your money to invest.

Many people will find it hard once bitcoin is gone. Many people are hoping that they are going to earn big in the future.

Is there a way to avoid these people from such fork even if a group of people supports it, or once the wants to have it activated no one can stop them anymore?

Will it still be decentralized? Once each state has their own coin then it will have less damand because it is state specific.

N.Kor will probably not stop developing it's nuclear arsenal. Because they use it as leverage to other 1st world country as a bargaining chip. the only way for them to stop if it's own people revolt for freedom and reunite N.Kor with S.Kor.
