If there are any possible? I keep 4 backup file in same fold. 2 address lose and 2 address still there. And I use 2 FA. If thief stole backup file. Must 4 address all lose. Am I right?
It's hard to speculate. Assuming this is due to a stolen wallet backup file, it would make sense for the thief to sweep all addresses in the wallet simultaneously. However, you don't know how many keys were in the wallet when the thief may have had access to it ... he/she might have waited a long time for funds to accumulate before swooping in.
I did some transaction following and it appears your thief is accumulating loot in the address
