during my tourist stay in south africa in 2018 with my wife and my cousin, we were about twenty kilometers from the city of johannesburg when my cousin was bitten by a black mamba. We took him to the nearest clinic, but they refused to inject him with the anti-venom until we had paid (the anti-venom serum cost 1700 South African rands, so about $150), unfortunately we only had $50 cash on us and no credit card. I had my Coinbase app and $85 in bitcoin in my account, I tried to convince them to accept bitcoins as payment and they finally agreed. So I completed the payment for the serum with my bitcoins. Unfortunately my cousin did not survive. Rip tommy
