Some people don't see Bitcoin as a normal currency and think it's too risky because its value can change a lot.
Actually, it is normal to think that Bitcoin is too risky, moreover for those who don't really understand Bitcoin. It is because of the high volatility and fluctuation. Additionally, some people still don't understand much about how to utilize fluctuating markets optimally to gain profits. So, this is once more, normal to think like this.
Nobody knows for sure what will happen to Bitcoin in the future, but people are still talking about it and interested in it.
Everything must have its plus and minus sides. Some people always believe in Bitcoin, which can be really useful as a global currency, for worthy investment, and also for its great development.
However, o the other hand, some people who hate Bitcoin will always gonna hate whatever the reasons. And they will always spread bad news about Bitcoin as usual.
