If SegWit2x gets activated then your benefit would be lower transaction fees and faster transaction confirmations. SegWit2x aims to up the amount of data carried per block (up from 1mB to 2mB) to allow more transactions to be carried by each block.
Whether or not it gets implemented is a different story and its effect on the BTC price is yet to be seen.
Just make sure that your coins are held in a wallet that you have full access to the private keys and you'll be fine.

Based on my little understanding of Italian I think the listing also mentions that if the buyer wants to pay in BTC the seller would accept €300,000 worth.
I agree with you. The price in BTC should be equal to if not lower than the asking price in FIAT. Charging a higher price if being paid with BTC suggests that the seller would convert the coins to FIAT upon sale.

It'd be interesting to hear your analysis on what makes you think that $4600 will be the baseline price. Don't get me wrong, I think we'll be seeing a new ATH very soon but that's not to say that it won't have its hits too. Sub $4000 is still very possible. Either way, buying at around the $4000 or $5000 won't make much of a difference come 2 years time. Both would be considered bargains 

From the looks of your OP it sounds like you have no experience in this whatsoever and have nothing more than an idea that you want a team of people to implement.
ICOs are not get rich quick schemes. First 'sell' your idea to possible partners and try to build a small team first. You only opt for the ICO when you have a clear project outline and are in the final stages of releasing your token.

Why would anyone use this site? The site isn't well made (looks like it's using a standard script) and more importantly isn't open source. There already are plenty of more user friendly paper wallet generator sites that also feature nice designs that are fully open source and trusted. Anyone who suits this site is risking the fact that the keys could be compromised and backed up by the site owner.
You've got a lot of work to do if you want the site to be taken seriously.
GL!

I would be all over this had I not just spent half of my 'not to be used on collectibles' fund for the year 

An ICO lets you fund your project while still in its infancy.
Development of coins/tokens costs a lot and many projects have unforeseen costs. An ICO allows you to fund your project while it is in the making.
It also gives you a good indication of the future popularity of your project and the ability to respond to constructive criticism offered by investors.

It reminds me of the house pricing bubble that has hit the UK in recent years. The trends show uunsustainable growth as the rise was continuous and not showing any signs of slowing down. The nature of most assets is that they work in similar patterns. If there's too much growth over a short period of time, once the 'hubbub' dies downs, the price will correct itself and revert to a 'normal' price point. 
The only problem with applying this to BTC is that BTC is different to all other assets and has continued to shock economists. Don't take their word for it because you can rest assured that BTC will be noticing new ATH in the near future.

There's definitely been a lot of good news surrounding the price although the typical haters are calling it a bubble waiting to burst.
In terms of buying in, if you're simply looking to make fiat back on your investment then the number one rule is don't buy more than you're willing to lose. With that approach now would be the right time to buy.
If you believe in Blockchain technology and the likes of BTC then the price you buy in at shouldn't matter.

Thanks. Do you know how much they were selling them for when they were available?

I can't see these on the titan site. What was the sale price of these?
Edit: Bid retracted with OP's permission.

Shots fired  
Personally I think it was quite constructive. I'll try working on it for next time.
While you're dishing some advice, I'll do the same. Maybe you should buy legitimate items and not encourage cheap illegal activity all for the sake of a hundred bucks. It's nice if you to warn people but at the end of the day you were buying items obtained through SE.

An actual idea... Something new and useful that would actually be worth investing in.
ICOs are all the rage nowadays. A new 'coin/token' seems to launch on the daily. Majority of them are useless clones just looking to make quick money through an ICO.
You can advertise a coin all you like, pay for a signature campaign and the like, but at the end of the day what will actually make the ICO a success is if the coin actually has potential.
The people buying into the ICO want to see something worth investing their money in.

Cash out to BTC or to fiat?
Either way, both are very easy. Most coins/tokens are listed on at least one (usuallly more) exchange(s). When you want to 'cash out' all you have to do is make sure you've got your funds on the exchange and then execute a trade for the current value in BTC.
If you want to cash out to fiat then all you need to do is transfer those coins to an exchange that lets you trade BTC/USD and then withdraw those funds to your account. 
 

You were buying SE goods. If the seller hasn't responded then you can assume that he's gone awol. There's no use crying over spilt milk. You kind of have to expect something like that to happen when buying goods for less than 50% of there sale value. In future either use Escrow or keep to official and legitimate sales channels.

Coins on eBay are overpriced and don't always end up getting sold. The risk of selling funded Cas coins on eBay coupled with the high fees (10% eBay fees not including PayPal fees) is astronomical.
Regardless, youbcant really compare the price of a loaded coin to an unloaded one. There is some demand for redeemed Cas coins but as already mentioned, $250 is the best offer you'd get for a coin. I'd take that if I were you. I don't think anyone on the forum would make a higher one than that.

What would the point in going do be? Unless trade would be primarily localised, there'd be no real absolute benefits in doing so. In a way it would actually be a move backwards. If countries were to opt to switch between fiat systems tonfigital tokens then it'd be much more efficient to have a universally accepted token that would facilitate international trade.

In order for something to be a zero sum game one has to win while the other one loses. In truth no kind of trading is really a zero sum game. If a person buys shares in a company and the shares go up, everyone wins. The exchange are just facilitating the trade so there's no real lost. The only thing you could suggest is a possible opportunity cost for new traders buying in at the new price.

Dear. Don't know that they released new coins.
