Hi, I am new to ARK and looking for a place to park my investment for long-term.  I have a few questions hoping anyone who's knowing Ark well to give me some answers for the following questions below:

1. Is Ark a competitor of Stratis, Waves, Ethereum, Lisk?
2. Is Ark built to host ICO's.
3. If Q2 is yes, when will it be able to, give your best Guess?
4. Why do you think Ark is a must have long term investment?

Thank you in advance.
