Many people buy bulk weed from DNM but this would require one to get thousands of dollars worth of bitcoins. Which is hard to do because you can only do so much bank transfers, WU transfers or moneygram transfers...
I don't understand how people can get this amount of bitcoin using lbc or coinbase without it raising any flags.
Any advice?
With so many people using BTC for legitimate reasons these days it's no red flag to make such a large purchase. Even if it did raise any red flags, stop and think about how many resources would be expended on just a single investigation trying to make any connections between illicit transactions, much less trying to prove them. It's simply not feasible.
