You should know by now not to listen to o_e_l_e_o, he will say any lie necessary about privacy software on order to trick people into losing their money to a custodian instead. There is no "flaw", stop FUDing:
Don't take it personally. Kruw has been ignoring stuff he doesn't like or can't answer for the best part of a year now:

Step 4 - Go to Step 1
o_e_l_e_o, didn't you hear Peter Todd?
