Do you need QR code for your paper wallet, or it is enough if you write down the private key _manually_ with pen on a plain A4 paper and after you laminate it? And put it into a safe afterwards, and later on if you need it, you just need to read ther private key from the paper? Can you use mycellium without QR for cold storage or it needs QR format anyway?
If you scan a QR code into mycellium, won't it remember for it after? How can I be sure that it does not store my privare key?

Thanks. I wan not aware about this. It means that they shuffles the cards had already been played too, not just throwing them away? In this case you have equal chances in all rounds. Is this the practice in case of poker too, or in that case it doesn't matter because of the different rules?

Thanks again

How long does it take to learn to count the cards in blackjack? Or a simple excel sheet is enough (if I play online)? I know the basics of blackjack but I'm not a master of it yet. I know that google can find tons of pages even youtube to teach how to play but I would like to know if there is any specific that I should know if I play online?

What are the prices (roughly) of these cold hardware wallets? Is the cheapest for beginners, or the price doesn't reflect the security of it?
Do I think well that if you print a paper wallet, you can add funds to it while the paper is hidden somewhere, you only need to use the paper only if you want to spend from it?

I haven't try to withdraw money from ATM yet. As I understood from the official topic of XAPO here, they doesn't charge hidden fees. They only charge their official fee, which buils up some of their fee and the fee of the ATM network usage. The card issuer company has a dedicated page for this where you can check the actual fees per transaction. The rates are nearly the same like if you use your fiat card in a different bank's ATM.
I use only POS purchase in shops because it's really free.

On short term, some of the people (lucky ones) can win, some of them lose. It is only interesting from the point of view of the single person, if he had won or not. The house edge is always there, doesn't matter if we talk about shortnor long term. So if you want to win, you should be quick enough not to let your profit get vanished by house edge on the long run.

Thanks for the clarification. In this case this game is just equals (taking into consideration the chance to win or lose) to slots and dice etc. In this case you can't prepare for it, it is also pure luck based. Because of this, there should not be any strategy to win ot, defenately.

What if some other countries also ban the bitcoin transactions? What was the reason in Russia? Lack of control? In China, most of the people was also involved in a state driven stock exchange hype where people were buying lots of shares as a kind of gambling. This lead to increase in price on the short term but after there was a big fall. I don't know if it can have any connection with the increased traffics of the bitcoin exchanges or not.

You're right, I am trying to restrict myself of using it frequently, because of the hard earned bitcoins, but sometimes I just buy a coke or something, just to be sure that the system is still working But if somehow I would get a monthly income in bitcoin, it would have been just normal to do the daily spendings with it. Until this happens, I just consider it as a possibility to spend bitcoin with, if needed.

I use XAPO's wallet for daily spending, just because of the debit card linked to it. I can pay directly from my bitcoin wallet, thru VISA's system. They have a so called cold storage as well (vault, and they say that it's insured somehow). But if I would have a really lots of bitcoin I would have use a phisical cold storage. I don't know if it would be paper wallet or Trezor kind, but I hope that in the near future I have to think about this dilemma

I have read a bit in wikipedia about minesweeper and it is quite interesting. There are researches about minesweeper strategies, patterns and other cool stuff. It gives you hints how to start the game and how to recognize the patterns during the game.
It also highlights that in some cases you just can't predict the mine's proper location with any of the strategies or patterns, you have to guess. This is where luck comes in and this is why you just can't build a real gambling strategy on it.
So no magical trick or strategy for this too, unfortunately.

Thanks

What about transaction fees? Miners can get some bitcoin for processing transaction also. Does it not worth them to stay in business? As usage of bitcoin grows, there will be more and more transaction needs to be processed. Maybe the priority fee will be normal in some time because of the miners' capacities.

I have a XAPO wallet and have got a debit card attached to it. When I use my debit card, it exchanges the exact amount of bitcoin to fiat and that's all. Merchants accept it because it's VISA and they don't know what is happening behind the scenes (and tjey don't care, even if they know, their business is with VISA, not XAPO).
I have tried only POS purchase but others said that you can withdraw money from ATM as well.
Maybe this can be a temporary solution until merchants start to accept bitcoin directly in the future.

And what about the transaction fees? If there will be 50% less miners, they have to process the same amount of transactions like before halving. Transaction fees should rise or the process time should get longer if transaction fees doesn't change.
Today if you want to urge your transaction you can choose priority fees or if you have time to wait you can choose economy fees, there is a difference that is noticeable already.

Maybe in case of poker, the strategy can beat luck on the long run. It's possible that in very rare cases a royal flush pops up but the chance of it is really low. When the other doesn't have the royal flush but something lower, strategy wins.
It's really skill based game, in 95%. The rest 5% can be luck. But 5% luck and 100% luck makes difference when it's about your bitcoins.

Thanks!

And what about the miners' equipment? Today it doesn't worth to mine with graphical cards anymore, only with special equipment. If you mine the same time, use electricity, and you find half quantity of bitcoin, the price should increase to let miners stay in business.
What about transaction fees? Will they increase as well after the halving as well?

If you prepare for opening a position (analisys, research, etc) it doesn't matter how long you plan to leave the position open (daytrade, swing or long term) and if you use some stoploss method than it's not gambling. Daytrade is not only in forex market, you can buy and sell within a day on the stock market as well. So daytrade requires the same skills as long term trade or even better, because you have to react far more quickly to win, because of the narrower stop limits (on long term you can use bigger stops to catch the long term trends and not to be stopped by short term corrections meanwhile)
