I assume you are willing to take a higher risk to be able to achieve this kind of exponential growth.

If you want the two alts that have the chance to absolutely explode I recommend Pearl (PRL) and Shell (SHL). As soon as PRL will be pegged to a fix amount of storage, most likely 64GB, it will be one of the few tokens with intrinsic value around 7usd.

That seems outlandish given the fact for how little it is being traded, but there are also some issues with the project, main net not running without limitation, even though these are also due the Iota tangle not being ready but they work on it.

As I said, not without risks but tremendous upside potential and the projects are disruptive to entire industries.
