If you have made the 50 krill for chat privileges in the chatbox there are some trustworthy people there who will sell you chips for Paypal or cashapp type transfers if you can't transfer btc to the site.
Ask around and you will soon see who can be trusted and who cannot.
Chatbox speaks, chip transactions or selling i will be never support. But if there is a familiar person then different. Besides, I would tell each person directly transfer BTC to the SwC account or deposit it. Because BTC can be easily deposited. And if you are facing a problem for any reason, contact the SwC team directly. This is the best way. It will not be harassed and There will be no fear of being a scam.
Bitcoin is easily bought and deposited, but buying small amounts can have big fees depending on where you live. Also, some providers will close accounts or restrict them if sending directly to a gambling site, so you have to send to private wallet first and then from there to the site.
For someone buying a few hundred chips to play small stakes the chatbox is often the cheapest option. May not be for everyone but it works for a lot of regulars on the site.
