Do you think if BTC had a stable price which could only be altered by $0.01-0.10 it would still be as popular and as used?
No I don't think that bitcoin would be popular if it had a stable price, as it is mostly used by investors and traders and also speculators, so if bitcoin had a stable price then they would have lost interest and bitcoin would haven't been so popular.
I agree with you, bitcoin will not be able to continue to popular if it has a stable price, people will gradually give up bitcoin and seek out new investments similar to what they did with gold. Most people like Bitcoin because strong fluctuations in prices, Bitcoin is the most famous on this point, this helps traders and investors make a lot of money, if it is stable, I believe that no one interested in it, stability is not earn money, it will no longer be popular. And want the price of stable bitcoin is very difficult thing because investors and traders are always looking for ways to make the price of Bitcoin change constantly, they are making money based on it, they will not let it stabilize
And with people you mean idiots, right? If you truly support bitcoin, you support it for its technology, not the price. That's a huge problem right and it is that most people are only seeking to get rich, make money fast and get out, they don't really care about bitcoin and they wont use bitcoin as what it is, a currency.
