In this case, there are two options:
1. Convert the neccessary amount of bitcoin on an exchange and send it directly to your CreditCard's account nr. There could be a problem with this at the exchange, because your EUR, USD, etc account has your name, but the credit card account doesn't, it's the bank's account to keep the details of the credit. So it's possible that some exchange won't let you wire money to that account.
2. Convert then send it to your everyday EUR, USD, etc... account. Transfer it to your CreditCard's account, and voila... problem could be that in some EU countries, banks started to monitor if a wire transfer comes from a cryptocurrency related account number and sometimes they send the transaction back without a question. So test it, before you spend large amount from your credit card, and always be safe to be able to pay it back from another fund source. You would never know that your transaction will arrive or not, despite of the formers has arrived without problems, banks are arising on the topic it seems...

Are you sure that cloud mining is a really good investment? I'm always wondering if someone has a huge farm of miners (ASICs or similar rigs), why is it a good idea for him to lend it in parts for a fee and pay a sum back as a mining profit? Why don't he just collect the profit for himself? Maybe because it's not as profitable as it's advertised?

Sure, shipping of the Ledger Nano S is a really long time now, 1 month for waiting to get your order processed and some weeks to receive the device physically. (If you choose DPD the second part can be less than a week). I don't know if it makes any difference in connection with the order processing time if you buy from Amazon or directly from the seller's website.

First, you should pay it off with fiat. After:
I would reverse the question, why not to use a bitcoin debit card if you have bitcoin and you want to use your bitcoin for spending? (paying card debt off is also spending purpose). Most of the cards are VISA branded so they are accepted worldwide. OK, bitcoin debit cards are not anonymous. But, if you pay off your card debt with bitcoin, tax authorities will surely ask about the origin of the amount you have paid off, so it also doesn't make any difference.

If it went already green, just set a trailing stop and you're fine for that trade. Trailing stop just follows the market growth, and if it turns down, it automatically liquidates your position preserving the accumulated profit. Problem is that Kraken has stopped using these kind of "smart" trade methods. The official reason was that their system was heavily overloaded and they can't offer this kind of service for a while (I hope that they're upgrading their system and it's not final...)

This is just a good start, but there's no guarantee that they will decide in the favor of bitcoin in the future. It's possible that they (as other countries already started) will also start to develop the digital type of their own  national currency, and in that case they would understandably prefer their own and controlled digital money...

It's OK that you will store your coins in a safe wallet but don't forget that you should'n hurry claiming the new coins, because of lack of the replay protection. If you haven't read about it yet, you should do a quick google about it. The most important thing about that is that you should move your real bitcoins somewhere in a different and secure wallet, before you start to deal (claim) your new coins. This is how you can ensure that if you move the new coins to exchange or to somewhere else, possibly fraudulent users can't move your original bitcoins from your original wallet parallel.

I'm not a trader. I'm just thinking simple. Now alts are down, because of bitcoin gold fork and because everyone is buying bitcoin. As soon as the fork is done, those who had alts will start to buy back the alts and hold it until November when the next fork comes. So it would be understandable if alts could grow a bit after this huge drop, before the next fork. But I'm not a trader, so everything can happen...

It's no use to talk about satoshies yet, because that portion of bitcoin is way too little (yet).
Today, average amounts are 0,1 to 0,001 bitcoins, so if you relly want to name it somehow, the bitcoin cent would be a good and understandable expressin for an amount of 0,01 BTC that's about $50 these days. It's understandable and acceptable for the masses too, I guess. Using the 'deci' or 'centi' or other scientific expressions would not be clear enough for average joes (like me ).

Just put your transaction ID into VIABTC https://pool.viabtc.com/tools/txaccelerator/ every hour as long as you have your transaction confirmed. If your transaction gets accepted in VIABTC, you should check your transaction in a few hours time, it should get confirmed sooner or later.
Usually it's possible to accelerate a transaction with a really low fee, so don't worry

Bitcoin is rising and alts are going down, as most of the people are selling alts to buy bitcoin, such high demand causes the price increase. If the people (were holding alts before) will realize the extra bitcoin gold after the fork, they will start to sell bitcoin to buy back alts, so price will decrease a bit. For long term holders it's not a problem, but if somebody wants to buy the very first bitcoin, maybe this is not the perfect timing...

You mean that banks will offer people bitcoin accounts, they (banks) will handle the private keys and people will be happy to use those accounts to manage bitcoin transactions? Why would they do this, if thy can do it now on their mobile app? Maybe, to store a large amount of bitcoin they will use banks, but only if bitcoin will be fully legalized in the country. Banks will change but not because of bitcoin, but because of digitalization.

Most of the people are selling alts and buying Bitcoin because of the coming forks, so the reason behind the price increase could be this as well. FUD and fake news will alway exist and as soon as bitcoin reach the mass adoption, prompt selling for bad news will be less common, and hopefully price will get less volatile as well. This won't be true during the coming fork period.

It's never a good idea to store large amount of coins on exchange, but sometime you just can't avoid it. Leaving just a little amount of bitcoin on the exchange won't hurt, as long as you can afford the lost (if happens). Sooner or later exchanges will give you the forked coins, it's just the matter of time (XAPO has offered BCH in early October, the fork happened in August...)

Cheer is for the free marketing, done by Goldman Sachs, mentioning bitcoin in a good context (opposite to JP Morgan, who put all the negatives on bitcoin few weeks ago). This is it, nothing special. Nobody want the financial giants to take over bitcoin, they won't, they're about to develop their own system based on ETH (see the EEA, some of the big banks are in). If they let their customers to trade bitcoin, they would legitimize bitcoin with this, and that's good for the wider acceptance, for the mass adoption.

Néztem a whitelist regisztrációt, de a kérdésekre, hogy miért érdeklődöm a dolog iránt, nem láttam olyan választ, hogy "Csak úgy" vagy valami hasonló általánost, valami orvosnak kell majd kiadom magam, hogy regisztrálhassak

I'm just wondering if the upcoming fork gives bitcoin gold in the case the bitcoins are in a segwit type address and not in a legacy address. I have read a lot about this fork, but found nothing about this specific question. Anyone has any idea, please let me know, thanks!

Bitcoin have to reach the masses before the digital fiat time and bitcoin needs to gain enough trust. If some government issued digital currencies start and get mass adoption, the trust in government and banks (which is not backed by any technical or material things, just 'blind' trust in the financial system itself) will give them real advantage.
