Bitcoin is volatile because there is a limited supply only and it is just 21 million bitcoins. It is also difficult to mine bitcoins because as far as I know it is divided into two after 4 consecutive years. I think that is the reason behind its volatility. Its price goes up when there is a great demand but the price becomes lower if the demand will goes down. It is a matter of scarce resources.
I agree with you!Honestly the Bitcoin maximum capacity was almost 21 million and then because of it's volatile movement it creates for up and down of it's value price.And not only for that because I believe also why it's volatile movement was most of the Investors tried to sell and buy their bitcoin everyday.This is a big reason and it is really true of all evidence that many Investors now is really interested for cryptocurrency especially for Bitcoin.But despite of that we should be thankful and blessed because until now the bitcoin was still alive and kicking to make as proud continue to our dreams in life together with bitcoin.
