An average bitcoin user can buy and sell for major sovereign currencies using online exchanges.so exchanges acts as brokers serving as a platform over which buyers and sellers come together or as dealers. Taking on an inventory of bitcoin to sell to users and profiting from bid-ask spreads. But how can bitcoin exchanges affect us ?
Actually there are another factors that we need to see before to say that we can use direct even after the ban/regulates .
Exchange are the big ways to make buy and sell of any coins ( available at exchange ) but at the p2p trading platform we need to work with particular coins .
Here we can take the example of the localbitcoins.com where people can buy and sell with better escrow services .
But if the government will restrict to the exchanges than surily they will get banned by ip , but to use those sites with vpn will not be better option for those who are honest and follow government guidelines .
So here we can say that a big part of the bitcoin market will get fluctuate due to ban of the exchange , and in that case we will needed ti buy those coins which get lowered by price and wait for the long time to became the Market again at stable and high price .
