I see that a few people have recommended for you to buy EOS. In my opinion it is/could be the worst coin you could put your money into. They are already changing the system only after the mainnet got released only couple of weeks ago. Probably it would be best for you to dyor and then make your mind.
I agree with you. I have seen a large pump in EOS in May, but after everybody expecting high rise on main-net release, but it did not happen, even it is going further down, but I think this is mostly due to BTC fall. Lets see how EOS rise when BTC normalizes.
