I made a purchase on a site called
kingkushweed and i sent $3920 bitcoins, now i think i shouldn't have place that much order for a first time, i think i might have been ripped off, Any way to get back my btc sent ?
You can't reverse your transaction and there is no way to do this unless you will contact the right person on that site and ask him to send back to you your deposit. That's why always be careful when you send money to invest, think 100x before making a final decision to send your funds.
