Here's how Indian techies are minting a fortune in bitcoins

BENGALURU: When 32-year-old Harshad Gawde first invested in bitcoins in 2013, he couldn't have expected the returns from it to sponsor an all-India tour, beginning with a six-month trip through Roopkund hills in Uttarakhand. He will be living off $15 daily payouts from that investment.
"I invested in bitcoin when one coin was worth Rs 28,000, one-tenth of what it is today," the Mumbai-based Gawde said. On August 30, one bitcoin was worth Rs 2,91,822—its value skyrocketing since Donald Trump's election as the US president in November and spawning an industry of auxiliary services for people rushing in to find gold in the virtual currency.
Bitcoin is a decentralised, paperless cryptocurrency invented by Satoshi Nakamoto, an alias for an anonymous programmer in 2009.
Unlike traditional currencies, crypto coins are not produced by a central authority like a bank or a consortium. It is a mathematical formula. These coins are produced by massively souped-up computers, called 'mining rigs', that solve complex math problems to obtain these virtual currencies. A ledger records all the transaction
