BitCoin does not offer all the things that some people want. It's not anonymous. It's traceable by design. It's online. It requires authentications, which takes a while.
There's lots of different properties one can want in a currency that BitCoin doesn't provide, and it's probably impossible to make a currency that matches EVERY wish EVERY person on earth has. States try that with fiat currencies and fail.
Yes but the alternative cryptocurrencies are like clones of bitcoin with another name. So they share all the problems of bitcoin and fix nothing
Then there is scamcoin, also know as microscam, wich is just a scam.
