Hi weVeg, i go one more step in Tor connection audit. The true is that i can approve that 1st min connections is not that secure (not information/data that you will share, it's encrypted, but connection you will use is not that hidden). Because we can get first node and exit node IP's. If ISP can catch that connection and your end IP with some backdoor, your are just owned. But when your ip change next time (after few min of active connection) you can't trace it again localy and that is point where Tor is best solution.
Tor is not broken, it's just how it was made from day one.
If you have time i can show you.
