"The matter of duping of several investorswith Ponzi schemes through Gainbitcoin website would be probed by the ED," the minister said.
He said Bhardwaj and his associates allegedly duped investors to the tune of Rs 2,000 crore in Mumbai, Pune, Nanded, Kolhapur and other places in the state.
"The main accused, Bhardwaj, has fled the country and a lookout notice has been issued for him," he said.
Another accused, Amolkumar Thombale, has been arrested while two other accused - Balaji Panchal, Raju Motewar - are absconding, he said.
The police has sealed thebank accounts of the accused and also seized Rs six crore, Patil added.
BJP MLA Ashish Shelar told reporters outside the Assembly that some companies allegedly lured people from Nanded and other areas to invest in Bitcoins, while promising higher returns.
"The owners of these companies are now on the run and investors feel cheated," he said.
"There should be a thorough inquiry by the Enforcement Directorate in the matter," Shelar said.
Kul said Bhardwaj had formed the company and invited investments in Bitcoins.
"As per my estimates, he has gone abroad and Rs 2,000 crore of thousands of investors are stuck," he alleged.
The company's directors also allegedly transferred the investors' money into their own accounts, which is illegal, Kul said.
Kul represents the Daund Assembly constituency in Pune district and his party is a part of the BJP-led government in Maharashtra.
