You MUST update to the wallet above by the 31st of August 2018 to remain relevant (PoS v3 fork).
Hi. Does this fork affect the coins that are in the exchange? or I have to transfer to wallet off
This should be done promptly otherwise u will be booted out of crypto. U need to prepare for harsh times, spare more food and earn dividends from people issuing them if u want to stay here and be able to fly overseas every year on a brand new jet. Being into trading will not make u better, it will only create a false impression of joy and fulfillment.
