By what year will we switch to Bitcoin? Is it possible in your opinion?
It's a speculative instrument. There are too few coins and too many people on earth for it to be used as a currency.
My feeling is that it will be used as digital gold to store money, and another cryptocurrency will emerge as an actual currency that people use. Which one that will be is anyone's guess. That's the whole fun of crypto investing - you just never know.
Yes, you are right, bitcoins are few, but we still have a "comma".Satoshi is a lot.
