exchanges are not required to be complaint to anyone and a court will rule that. unless you can show some serious proof as evidence to back up your claims of fraud
simply suggesting the exchange shorted a coin or two doesnt help im afraid.
crypto is largely unregulated and any money you put in here is really at your own risk.
1- It is not about 1 or two coins, Bittrex has recently, disabled thousands of accounts and blocked millions of dollars of deposits, in her interest.
2-There is no 'unregulated' business other than drug trafficking and alike, absence of specific regulations is not an excuse for a business to break general laws. Committing fraud and stealing people's assets is a general crime and can be prosecuted under general law.
3-In the cryptocurrency case, we already have laws that specifically identifies bitcoin and altcoins as 'asset'. Nobody is entitled to fraudulently play with people's assets and violating their ownership.
Im just speaking out of experience of course. Look at poloniex which is several times worse than bittrex, people have had millions of $$ stuck in polo for months.
Remember the FCT withdrawal issues, people hit withdraw on polo but the coins never appeared for weeks. Support ofcourse wasnt responding.
Many of these users threatened legal action, yet there is nothing there as of now.
Your best bet is to write to BBB or SEC and hope thinly for them to respond. Most of the time they see something related to crypto and ignore the entire complaint
About disabling accounts and such, bittrex will always claim they were not comfortable with KYC and had to disable the withdrawals. They can hide under this excuse for any illegal act they commit.
It will be a huge task to show otherwise that the withdrawal funds were more important than KYC
1- I think it is not about complaining to BBB or SEC (as Bittrex is not 'regulated') so, we should go directly to a court and nowhere else. As I have argued above this is not a violation of some SEC regulations, (there exists no such regulations) but can be categorized and prosecuted as a fraud.
2- They can't defend under the KYC article. Most of the stolen accounts are strongly verified and Bittrex is responsible for the KYC procedure compliance and not it customers. Obviously you can not accept people's deposits under a certain terms and conditions and then steal their funds saying 'Oh we don't know you, we are committed to KYC'
