Since Bitcoin is fixed supply, with the rise of the demand there's better chance for the price to keep growing, as average, over time.
Exactly. This is all that needs one needs to know to understand which is the more reasonable and intelligent way to invest. Fixed supply and increasing demand will naturally increase the price over the long run, while pump and dump alts like Doge are very difficult to keep track of, as once the hype created by people like Elon Musk dies, it will naturally drop down, most people that are into Doge aren't really invested for the long term/they don't really believe in the crypto. However, Bitcoin on the other hand has a wall of solid backers and unlikely to crash down to zero.
