Hi guys, I just want to know your views and opinion about the difference in Electronic Money (Bitcoin and others) and the Physical Money. Many people now a days are still confuse about the existence of the Bitcoin and how it differ from our Physical Money that we are using to buy necessity. I hope we could share and learn from each other. 
The different thing between physical money with bitcoin or cryptocurrency is on who control it. As we know, fiat money controlled by central bank, from supply and value but bitcoin is decentralized currency and no one institution can control and have limited supply
