The strongest directly relevant evidence is the PANews article titled 'Bitbase (币贝) 今日上线,拟以“机构级基建”与“纪律嘉奖”重塑市场黄金比例 | PANews', which explicitly says Bitbase launched as a digital asset derivatives trading platform, opened core trading, and that its matching engine and risk-control systems ran smoothly on day one. However, this is a secondary source and attributes key claims to official X posts. Those cited posts at https://x.com/Bitbase_cn/status/2041335154841440561 and https://x.com/Bitbase_cn/status/2041124138027548834 could not be fetched, so the official announcement itself was not independently confirmed in this run. The provided crypto.news article 'WhiteBIT secures broker license in Georgia' is unrelated and does not support the claim. Because corroboration attempts did not yield an accessible primary official source, the claim cannot be rated likely true with high confidence despite some supportive secondary evidence.
