Startup Idea : 1 Gram Gold Coin Vending Machine

I hope to make a vending machine that sells 1-gram gold coins. A 1-gram gold coin costs USD40.34 today (26 June). Gold is usually sold in bar which is very expensive (USD1254.57 today!). When it comes to buying gold, people think it needs a lot of money and it requires them to visit a classy jewellry boutique. However I hope to make a vending machine that sells gold in small amount so that it is affordable to most people. The machine will be placed in train stations or shopping malls which are places highly accessible to most people. It will be equipped with electronic payment such as Apply Pay, Alipay, PayPal so that no real cash is needed for the purchase. Why Gold Coins? Well bitcoin, litecoin, and ethereum are all digital currencies and their values are jumping up like crazy because people are flocking in for risk hedging. Therefore it can be seen that risk hedging is in very high demand, particularly when most governments keep printing money non-stop. I believe people need to store physically gold as well bit by bit in normal days and in times of financial turmoil or war, people can only turn to gold and rely on gold which will not be hacked unlike digital currencies
