China is considered as one of major country in this world. They mostly dominate Asian market in every areas.
Long back before China was a mess country because of dictator leadership.so it would make sense they are in the lead with bitcoin mining wince they have so many miners and cheap electricity as well to compliment their massive mining farm operations.

In bank there are other people who are professional investors and their job are trading with your money.bitcoin also risky, but you have the full control about buying or sellling it.

It is very simple many coins equals more profit, few coins equals less profit. but if you split it in different altcoins if one crash you can run to other.

Bitcoin is a crypto currency in the crypto world. this is a largest and a biggest cvurrency in the world . but, in  Today , bitcoin value is down. bitcoin value is not a stable.so even though now the bitcoin has decreased, surely in the next few weeks there will be an increase.

I think global regulations won't kill Bitcoin, it's not like these regulations are banning Bitcoin. bitcoin cannot die,it has gone through alot of ups and downs and it has come out strong.

Because Bitcoin will surely give us profit despite of the high price. Also, it is the most accepted cryptocurrency worldwide.  I'm still investing in bitcoin for the long term.
