A national fiat currency is given value by faith. That's all it is, plain and simple. People also have faith in crypto. Well, you don't, but who says everyone should invest in everything? As I've said repeatedly, we're not trying to get anyone to buy crypto. We're just trying to get people to understand it and to stop spreading FUD about it. I couldn't care less what you do with your money. Throw it in the toilet for all I care. If you made a killing in the stock market, bravo. I will never look down on a successful investment. I applaud success.
Currencies came around because bartering was too difficult. Money wasn't always around and bartering was usually simple in the case of small villages where there were few people. As population grew, bartering became more difficult to find the products you needed and to find someone you could give your products to in exchange. That's why currencies arose, a common base everyone could use that isn't tied to any particular product or service. It eliminated the need for bartering. When conditions exist, such as in Venezuela or Weimar Germany, people resorted to bartering again out of necessity since their currencies had less value than the paper they were printed on. That can happen to any economy if the stewards of the economy fail. The dollar is worth something because people have faith in the US. But is it backed by any hard asset like gold? No. Crypto doesn't have the faith people have in the dollar just because it is relatively unknown to most people. But that is growing. As I said earlier, over 600 million people own crypto, nearly double the population of the US. Crypto has value because the participants have faith in it.
Is crypto more volatile than stocks? As a whole, of course it is. Smaller markets make for more volatility. The entire market cap of crypto is roughly that of Nvidia or Apple or Microsoft in the $3 trillion range. Those stocks are pretty volatile, too, because they're individual companies amidst a sea of companies. That's why investment advisors always recommend diversifying. No smart investor puts all of their eggs in one basket. Every individual stock has a beta coefficient, telling how it moves relative to the entire market. If it's higher than 1, it is more volatile than the market as a whole. But those are also the stocks where you can get the biggest gains. No one measures a crypto beta coefficient, but volatility means higher potential gains and accordingly, a higher potential for loss. One thing you will never hear anyone say is that crypto is a safe investment. There are blue chips that are safer, relative to others, such as Bitcoin or Ethereum, but no investment is entirely safe, not even that < 1% you earn on your savings account because your bank could fail and FDIC runs out of money. But notice that the earnings are lower when risk is lower. Junk bonds have to pay higher interest than AAA bonds, just to compensate for the risk factor. Crypto is higher risk, but the potential payoff is also higher than the stock market as a whole. By all means stick with your safer investments. I don't discourage that. Everyone has their risk tolerances. If crypto is too risky for you, please don't invest in it.
If and when crypto reaches its projected $30 trillion by 2030, it will become less volatile than it is. That is inevitable with larger market caps. If it reaches $100 trillion, it'll be even less volatile. You're arguing against investing in something because it is a riskier investment than say, the S&P 500. If everyone had that mindset, there would be no Angel investors, no venture capital, very few small cap stocks, and so on.
