okay something is wrong here
i run wallet for almost 20 hours ...fine ... i got almost 10k coins
now after i shutdown my computer and reopen ... the wallet won't start .... so i backed up the ( default wallet ) deleted the data and resync
so ... after doing that ... somehow it seem that im with 0 balance and starting to mine coins from scratch
is there a way to know what is the actual balance of my wallet ... like block explorer
