In the past two months, somewhere in Nigeria territory promoted Bitcoin and Etherum to be used as a ponzi scheme pyramid. It crashes within 1.5 months and they started blaming each of them for falling into a big scam if bitcoin. They never understand how bitcoin works and they only keep saying bitcoin is a scam. Laziness and quick money earning is their number one priority agenda which is bad. Bitcoin and other altcoin can never be a scam because it's decentralized.
