Bitcoin craze: Amitabh Bachchan gets over $100 million top-up; wiped out in days

The crazy swings of Bitcoin prices added more than $100 million to megastar Amitabh Bachchan's fortunes within days, but most of it got wiped out even faster -- thanks to a small stake in a hitherto unknown firm associated with the web of cryptocurrencies.

There may be further such fluctuations with the craze for Bitcoins and other cryptocurrencies continuing to drive their prices and the regulatory risks remaining a big drag for the prices that saw Bitcoin skyrocketing to near $20,000 just a few days back before plunging back by almost half and then again recovering to $15,000 level.

While lakhs of Indians are said to have taken a fancy to the Bitcoin and other such virtual currencies, Bachchan is probably the first big name from the country to get associated with this big buzzword -- albeit indirectly and because of a small investment that is at least 3-4 years old.

The link is a Hyderabad-based company named Stampede Capital, which describes itself as a "research driven global trade house" and a "liquidity provider and market maker" at various exchanges driving "millions of dollars trading volume everyday across the globe in nano seconds". In its regulatory filings, the company lists Bachchan as an "individual non-promoter shareholder" with a small stake of 2.38 per cent at the end of last quarter. As per the BSE records, Bachchan figures on the list of shareholders (with 1 per cent or more stake) since at least June 2014, though the quantum he is holding has been changing somewhat.
