I'm comfortable with using Bitcoin but was wondering if it was easy to tell if a Bitcoin address is one used by a tumbler? I was thinking, for instance, that if this was easily discerned, could a wallet host "flag" someone who sends their coins through a tumbler? Here is my current set up:
Localbitcoins -> Cold Storage generated by bitaddress.org (offline of course) -> Sweep wallet into Blockchain.info -> Helix -> the trail goes cold here (hopefully)
The above setup is what I've gathered from my reading. Anyway, the thought popped into my head as to whether or not tumbler Bitcoin addresses are looked at by sites that host wallets? This is probably FUD, but was genuinely curious if transactions through tumblers were scrutinized or monitored to some degree?
Helix uses new addresses for each transaction so there is no way LE would able to tell which addresses are helix addresses. Once your coins hit Helix the one you get on the other side are completely new that is the whole point of cleaning your coins.
tldr; You are doing it perfect and have nothing to worry about.
