If the exchange rate is very volatile, there are many transactions in real society that are difficult to accomplish. I believe that with the development of the community, bitcoin fluctuations will become smaller and smaller.
There is mega risk if this happens. Actually bitcoins is known or differentiated from other sources of income Is just because of this fluctuations. If you remove them or slightly decrease them through any means, you could be seeing a loss and unimportant bitcoin world that isnt that much charming. This volatile makes the world of bitcoin different from others so we couldnt slow it.
