hi all,
Currently our tumbling options are blockchain's sharecoin, which i am having issues with. It is not loading the review payment button or the repetitions. Yes i have tried enabling scripts.
Another option is bitcoinfog, which is slightly expensive 1%-3% (~7-20dollars for 1btc)
You can register an account with an altcoin exchange (btc-e, cryptsy....) via Tor (or a random Wifi), buy altcoins then move those to an other exchange and buy Bitcoins. Usually no verification is needed if you only move cryptocoins in/out the exchange and fees are low, 0.x% depending on the exchange.
If you use Tor it's better to test the whole process first with a small amount because exchanges might accept deposits from Tor nodes but withdrawal is an other question.
