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 
You have a point mate but i don't believe in the notion that Bitcoin will run out of the system since only 21M BTC were created. Remember that Bitcoin is still in the beta stage and there are yet more developments to be fixed in.
