While we await the official clarity to which deposits currency qualify for the $100 to get $30 bonus, it is also best to assume, based on Scora's mode of transactions, which is multiple currency flexibility.
There is no need to wait anymore. Immediately after the post of mine that you quoted, SCORAS (OP) confirmed that bitcoin deposits worth $100 and more qualify for the promotion. There seems to be an unrelated cashier issue though that is affecting bitcoin deposits as some users have reported. Once that's been sorted out (maybe it already has), then you will be free to deposit and participate with bitcoin deposits.
What people need is to scroll up a little bit and they would find the answer by Scoras representative towards this inquiry.
Now its up to them if they want to use their BTC to qualify in their promotion.
BTW encounter a withdrawal issue as I try to withdraw my funds via Tron, but unfortunately it didn't credited on my wallet.
Well I'm amazed how fast their representative helping my case and answering my question, I will just wait on their updates then see if they can credit my withdrawal request.
