The SEC reported that Wajanasathian had purchased around $61,000 of Bitkub Coin ($KUB) just before it was publicized that the Siam Commercial Bank would purchase a 51% stake in Bitkub. After the announcement, the value of KUB rose 100%.
Earlier that week, the SCM had announced they would not be following through on purchasing the planned $500 million stake in Bitkub, due to concerns over "various issues" that were raised by the Thai SEC.
