I am not sure that this section is right to post my thread .
my question is :
since it was already fixed by the bitcoin owner network that
21 millions bitcoin can exist in the whole internet But now I heard that now the mining of the bitcoin will be unlimited , I mean unlimited bitcoin will generate by the bitcoin network .
If this is real news then
the value of the bitcoin will go down speedly It is because the supply is unlimited so it is simple to say that bitcoin price will no more increase rapidly ., so
no more profit what's your thought guys 
Well one of the factors or problem of bitcoin is the volatility price of it the unstable price of it which the demand on marketplace going ups and downs, but some is bitcoin volatility is an open opportunity.
And the second I think the risk , taking the risk is part and bitcoin is a risky investment , sometimes because of risk it's taking a big loss to some , and some are big income. So what I'm trying to say it's normal to have a problem but this doesn't mean to stop believing bitcoin.
The volatility of the price was created because we don't unite with one decision, the perks and negative outcome of free to do decision here, but at some point that volatility of the price has been the reason for some people for them to get successful in trading.
