I'm not talking about these supposed stablecoins like Tether, but normal coins. Let's say an agreement was made among all the major Bitcoin exchanges. Starting January 1, a Bitcoin is worth $5000 USD, plain and simple, and that's it. The price never goes higher or lower. A Bitcoin is $5000 today, tomorrow, next week, next month, etc. NOTHING changes it. Not a war, not the economy, not Trump getting re-elected (which he will, he's doing a great job), nothing.
I wonder if that could be done and what the effect would be.
One effect is that I wouldn't be buying BTC, because with no price volatility, how could I ever make a profit? But one good thing is that normal companies may be more inclined to use Bitcoin, since its price is now fixed and does not change.
There are some coins called stable coins and that not necessarily means that its market price is stationary and constant, though there are also coins that are limiting the sell price to a certain amount to avoid getting dumped and also its market price is not stationary and constant, in conclusion, there are no coin with price locked in place as market decides how much would it be.
