if a 2x-5x is your target I dont think IOTA is your go to coin for the time being.
Agreed. But only if you are holding for no less than 6-12 months. But in a year or two IOTA it is most likely to make it to the top 5 or 3. The future is very bright with IOTA and the Tangle technology. And the recent partnerships with big companies like Bosch makes me shill it more.

Yes. A balanced portfolio requires at least ETH or BTC as 25-30%.
