Are you asking folks in internet how it's better to control your own money? Perhaps we all are ICON's employees and were paid to advertise it. You should use your own logic and judge by yourself.

If ICON is a real project and they are going to achieve what they said in Whitepaper then yes, holding is the best option.
Unfortunately we have yet no clue if it's real. What have we got so far? They sold their tokens, the price has been pumped up as the result of speculations and promises. It has no real value at all because they haven't launched a shit yet.

They claim they're going to work with a Korean bank or something like that, but there are no proofs of it! We can only trust them. Do you trust people which you don't know?

Do you realize what actually is happening? If they either delay or don't give people a reliable response about the net launch, the price will eat its shit.

The actual motive is to find out whether they're trustworthy or not.
If you have a toothache you go to a dentist. You don't go to a random person that pretends he can cure you but you go to the one you trust.
My point is that if I'm investing money into something/someone, I'd like to be sure I'm dealing with a professional.

Is it? There's no blockchain network of ICON so far. They just claim it will be the one. We haven't got a clue if it exists at all or they're actually working on it.

It's cool to be cool when you're having fun. But now we all are trying to make money here.

Hello.
I've just started learning cryptos and perhaps don't understand basic things.

What actually makes you believe in ICON? I'm hodling about 1000 ICX myself but in a doubt now.
What makes you think that it's not scam at all? Have the team proven they got "the product" at all? I mean it's all now just according to their words. They said they are launching the main net at Q4 2017. What makes you believe that they actually got it and really are about to launch?

Also, googled their team and couldn't find any links to their LinkedIn accs. Theloop team, as I believe, is the core team of the project, claims that they've got a partnership with Samsung on their website. However I couldn't find any reliable proofs of it.

Idk.. it seems very weird to me. Perhaps it's normal in crypto's world.
