However, judging from the highly praised comments in the comment area, it seems that there is still a long way to go in popularizing science 😂 For example, someone asked: Stablecoins can be issued at will, so can Geocentric Coins be issued to bind to the base currency? Someone asked: Do stablecoin companies take a large amount of money from everyone without interest for investment? In fact, both answers are very simple: Answer 1: Base currencies are indeed issued at will, but if your recognition is not good, it is a waste of time. If you really want to issue recognized base currencies, You need to have a large number of base trading enthusiasts. You need a very compliant institution to help you custody the base currency, but this is impossible. Answer 2: It is indeed interest-free, and the first half of the sentence is correct. The second half of the sentence is wrong. Stablecoin companies cannot invest at will, and can only hold highly liquid things such as cash and short-term US bonds.
