millionaire from nothing? no way
The only way to do it is to already be one, and start investing, pumping and dumping thousands of dollars per day, like these Chinese guys at #1 on Okcoin
For all of us, the average Joes, the best case scenario is to invest $1k in an altcoin you follow by its' babysteps and get something like x100. But that doesn't happen everyday, so either keep looking or start searching for new technologies unknown to the masses like blockchain once was.
That is the only way to do it.
Buy in early at $1k to see it grow and make a ton from it then sell off.
