i was staking a few times, then when there got to be around a dozen inputs i would consolidate them back into one. not sure what the best strategy is, and things might change with the new wallet.
the problem is ,my wallet will stack once only (... so i have to send coins myself to stack again for one time
... if i close and open the wallet does it affect stacking process?
it should stake more than once over time. opening/closing the wallet shouldnt change anything, but leaving it open longer and unlocked for minting will help your staking odds. make sure you backup your wallet, we'll see what the new wallet is like in about 4 days.
