It doesn't cost any money to get registered with FINCEN.

Depending on your state you may not need a state licensure. Getting registered with FINCEN and implementing an effective AML / KYC policy is not particularly expensive, if you do it yourself, but it may be time consuming.

If you pay a compliance company to do your AML / KYC policy for you, it may cost a grand or so. But, you can also do it yourself, if you want to invest some time into research, effectively accomplishing it for free.

I am just giving advice to keep any future would-be BTC sellers from having all their assets seized by the feds incase they decide to go after you like they did Burt.

FINCEN does give a 6 month grace period before you are required to register, it says so on their website. But if you are selling BTC long term and doing any somewhat significant volume of local transactions you should probably register as an MSB and follow AML / KYC policies. Unless you want to take the risk. It's up to you.

I'm just saying, if you are doing really low volume, it probably won't matter. But if one day they decide to prosecute BTC sellers in your state like they have in FL and CO, this could very well happen to anyone. But you can prevent it by being registered as an MSB with FINCEN (which is free) and implementing an AML / KYC policy. For your AML policy, you probably won't be able to do transactions over 3k unless they provide ID and proof of residence. It would probably be a good idea not to do any transactions over 3k, period.

If they mention using the BTC for anything illegal, it's a good idea to assume the customer is an undercover federal agent and you must terminate the transaction immediately.
