Everyday, we are seeing new crypto currency exchanges start working. So many platform has already opened. But Is that OK? I think volumes are seperating. How this effect prices?
New exchanges without real products of the coins won't make any difference, it just spreading the volume indeed.
But if there are new exchanges coming, usually they have some events that you can participate to get rewards in coins or tokens.
Many exchanges in the crypto market are not survived if they have no volume in their exchange, so they running events to get more users.
