CoinHako is a Bitcoin brokerage business that has processed a million dollars in volume since its inception in end 2014. Our users transact with peace of mind since we became the first service in Asia to have reserves insured against theft/hacking attempts. CoinHako’s engineering team is also focused on innovations in Bitcoin’s underlying technology, the Blockchain. We have built tools to detect suspicious/fraudulent transactions and trace them back to the source for further action by relevant authority. The technology was awarded a winning position at the inaugural Blockchain hackathon organized by DBS Bank in Singapore. CoinHako’s technological capability and business acumen have attracted financing from investors in Silicon Valley - namely Tim Draper, Josh Jones and Boost VC. The team is stealthily developing financial services on top of their core infrastructure.
