I think I have found a way to access my JPC... I have over 100k transaction in my wallet so the client gets so slow its impossible to use the client or it simply crash.
How ever I found a way to move the coins to a NEW wallet with a NEW address.
Will that destroy my staking/minting since the coins I have is OLD most from 2014... and I assume they will become brand new. Does that affect my staking in some way?
