If the price of EOS were to reach USD$0.5 I would buy with everything I plan to invest, for a variety of reasons:
The price on the markets is likely to be artificially inflated like you mentioned, due to most coins bought during the ICO cycles not making it to market.
Dan has already produced two utterly incredible platforms that are continuing to grow in success. Now that he has the kind of funding behind him that is almost unimaginable outside crypto, I am expecting something phenominal.
EOS price will continue to climb forever provided the platform gets adopted more widely. Anyone wanting to use the platform needs blockchain bandwidth awarded to them by the tokens. This seems like a great long term hold.
That being said, if any of the above don't hold water I would love to have a discussion about it. ICOs are always uncertain and it helps when several minds meet to build a better understanding.
