Because there are some unknowns around the time of the fork (upgrade) at Oct 1 2019 at 16:00 UTC, Id recommend the following:
Store your RVN on-chain in upgraded software. Get 2.5.1 from here:
https://github.com/RavenProject/Ravencoin/releases and transfer your RVN to it. Any other upgraded (non-custodial) wallet will work also.
Remove RVN from custodial accounts by sending to an updated wallet, at least until this upgrade is complete and everyone is on the same page. Examples of custodial accounts: Binance, Bittrex, (other exchanges), Crypto.com, Spend.com.
Do not transfer RVN until we have a good sense that everyone has upgraded. These are just recommendations, but it safer not to send RVN from Sept 30th until a few days after Oct 1, and we know who has upgraded and who hasnt.
Dont buy or sell any RVN to/from anyone, including exchanges that you dont know have upgraded. Wait until the network has stabilized and everyone knows where everything stands.
