bitcoin just an internet money and dollar is a real money..
the main things in here not many people understand in btc especially our parents..hard to explain..
This is the most confused notion that people tend to have. Dollars, Euro, and every other fiat system
IS NOT REAL MONEY.
Central banks in every country creates what you think is real money out of thin air. It's literally paper that doesn't represent anything of value, yet, it is supposed to be a value of whatever denomination it has on the note... which is backed up on the "trust of the government".
Money and the market systems is guided by the "invisible hand", which used to be backed by gold... now it is backed by nothing. Every dollar you have in your wallet and bank account is essentially worthless in all actuality, just as of right now you need it to purchase real world goods and pay bills... but the hope is to be able to pay for goods, services, pay bills, pay taxes, etc with crypto (which will hopefully be backed by gold, as well as cold hard, fundamentally sound math.).
I love how everybody ignores this hard point. Definitely, this is important to know that the only reason that the paper money has value is because the general public perceives that it has value.
Being backed by gold, if every single person tried to cash out on the gold, there would not be enough. There's not enough gold to support all the printed money that is in the world. At the end of it, it's all worthless.
