BTC price will drop to 0 as soon as someone invents a super computer that will be able to crack the encryption of the system, or if the whole internet will be shut down. Of course the chance of these are nearly zero, so as long as there is a proper demand, the price will rise.

Bitcoin should find it's place on the market in connection with payment processing. As of it's current speed when confirmations takes much more time then fiat card transactions and even more then cash transactions, bitcoin should find it's market share where this speed is acceptable and the cost is more relevant. One of this possible transactions is the international money transfer but maybe there can be some other possible transaction as well.
You can't use bitcoin yet in shops directly because of this speed, but meanwhile developers are working on a speedy direct payment solution (or I hope that they are working on it) we can use bitcoin debit cards to do speedy payments at merchants.

You are partially right in connection with anonymity. If you use BTC debit cards, your anonymity is over. If you pay in a webshop when they have to ship the item to you, you have to provide at least a name and an address, so that's not the anonymity again.
Of course you can keep your anonymity more easy compared to fiat card transactions but it can't be as anonym as cash, because it's using networks, devices, etc while cash is only a piece of paper and noone traces the route of the bank notes

There is no free lunch on the market. Everyone wants to earn it's portion the question is what is the amount he wants to earn. The spread is less conspicuous if the amount is not $1k but less. In real life usually if you exchange currencies above a limit you will get a discount in the spread (better exchange rate). Maybe it should be considered by the service provider in the future, just not to lost it's customers, or the bigger ones at least

XAPO provides web based wallet (and android, ios, etc) with all the strengths and weeknesses of this kind of service.
If you want to use XAPO's debit card solution for it's original purpose like paying with a VISA card at merchants, you should do the same like with your fiat card. E.g. if you have money, let's say 10 (not EUR, USD but just 10 as an amount) If you use your fiat card for daily purchases and you use let's say 1 money per month, you won't put all your 10 money on your card's account but only 1 and you put your remaining 9 money somewhere onto a savings account or you buy stocks or just deposit it in the bank for a longer term for some interest to gain, etc.
But the most important thing is that you can use XAPO's wallet and card and you should use that with the same considerations like you do with your fiat card. You should not put all your Bitcoins into your wallet. You should not write the PIN on the card, you should take care of the card and don't lose it, etc. If you use it like your fiat card, it will be fine.
In this case you will only risk (if it's a risk at all) only the amount of your bitcoins you keep in your XAPO wallet.
For the rest of your bitcoins, there is XAPO's vault, but if you use the vault you still don't have your private key, so if you want to be 100% sure that nobody can take over your bitcoins you should find a trusted wallet you can handle your private key with. Or you should buy a hardware wallet to keep the rest of your bitcoins in.
If you use this solution you will have a desired amount spendable in your XAPO wallet with a VISA card, and the rest of your funds are hidden somewhere and noone can touch them.
If you think about an example from real life, you won't put all your savings in your leather wallet and put it in your pocket, when you go to a market where you can find a lot of pickpocketers... If you use your everyday practices in the bitcoin world, you can't be wrong.
Sorry for writing an essay

I have heared several times about this heads up display. Is it a software or a hardware? Or it's like the google glasses with specific application installed on it?
Is it really true that most of the online poker games are users vs. maschine? In this case only the best players can win online against the AI

Which one is better for you it really depends on which end you are on, e.g. if you are sending money and awaiting for an item to come, Paypal is suitable for you. But if you are the sender of the item, you would prefer irreversible money transfer and that's Bitcoin.

Risk and possible reward are always go paralell. If you don't want to take risk because you are a conservative or cautious player, you can expect less reward but if you are this kind of personality, this reward should be enough. If you are a risk taker, you can handle the bigger risk mentally, you can expect more reward. But this does not mean that if you can expect that bigger reward, then you will get it automatically, because of luck. If luck is against you, you can take that risk in vain, you won't get any reward, but loss. And luck is the factor you can't influence, this is gambling about. Someone wins, others lose.

Try to make an opening video, sometimes it helps. Or, if size matters, you can measure the envelope and check if the item would have fit in it if the scammer really sends it. If the envelope is smaller then the item, it's another fact to prove your right.
Another thing to consider. A friend of mine has received some little plastic something (like an earphone dust plug for a smartphone, so basically a little nothing) instead of the phone itself. He opened a claim at paypal, and the decision was to send that little piece of plastic back to the seller (buyer pays return post of course) to grt the money back. Post was nearly equal to the price of the scammer's item, so sometimes it's better if you receive an empty envelope

That's not 100% sure, but most likely. I had a situation when I have bought a cheap but very good looking phone on ebay with decent specs. Next day the feedback started to show up that the seller is a scammer. The seller has not sent anything after the payment, so I have opened a dispute in Paypal. After the dispute, the seller have provided a tracking nr. which was legit. Dispute has been waiting for the tracking nr. to show if it will be delivered to me or not. A bit later the post delivered me a small envelope, I have signed that I have received it. The seller has sent me an empty(!) envelope just because of the tracking nr. to Paypal. That moment I thought that I have lost my money, my luck was that if I order something above $10 I always do a package opening video. With this and with a lot of phone calls to paypal and much more email conversations, I have managed to get my money back, despite of the proof of delivery, but it was a long fight and a lot of hassle...

Payment received quickly as always, thanks.

Maybe stock trading has less risk but usually the amount you play on stock market is bigger than in gambling so at the end you can win big and lose a lot in both places. Gambling is instant win or loss however stock market can give you time to think over your decision and act again if needed.

Maybe people doesn't really look for a bitcoin bank for just itself and for the banking services but only looking for a safe way to grow their savings like in real life which is a bank that accepts deposits and gives a little interest on the deposited amount.
Maybe people who have bitcoin in their wallet just think that their bitcoins should grow like real life fiat savings.
But real life money should grow because of inflation and bitcoin has no inflation, so practically there is no need for a bitcoin bank for this purpose, it's only that people used to put their savings in banks in real lifecand they're trying to find this in the bitcoin ecosystem too.

It's like you have a great daily job with high salary and the salary depends on the time you work on it. In this case you will be better hire a gardener, cleaning lady, go to a restaurant to eat something instead of trying to do these things on your own and try to save money on the above mentioned things. It's just doesn't worth the time, because instead of trying to cook yourself a three course meal you can do some business and with the same time invested you can earn much more money compared to the money you would save on the restaurant bill.
So if you have a different opportunity to earn more money, think it twice that you really want to start this.

Paypal good for buyers and bitcoin is good for sellers. I'm continously buying little things (from $1 to $5 max.) from China and because of quality, quantity and delivery issues I prefer paypal. If I was a seller I would prefer bitcoin too. Confirmation time does not count because as soon as you realize that someone ordered something you sell and you wrap it up and put the address on it, you will have the confirmation too, so you can go to the post office.

This is the same like stopping most of the addicting things (alcohol, smoking, etc) you just can't stop it from today to tomorow. It can be a slow process and it's possible that someone needs help to finish the process. When it's finished, it does not have to mean that the person should not gamble again anymore, the question is if he realize when to stop and be able to stop at that point.
There should be a kind of demo account on gambling sites like on forex sites for this purpose and for the beginners too

Yes, OK, but if he's playing for a long time now, and had luck, he could win some bitcoin since then. In that case there can be a strategy to protect those winnings or at least to lose them a bit more slower then the average. If we don't count his time that he loses anyway, this can be a safe method to gamble and also not to lose what is not affordable to. The other possibility is to lose every day what the faucet gives but not more and that also can be done safely, but in this case there is probably no strategy involved at all just pure luck.

OK, decision accepted, thank you.
You are right, I haven't made any bets because I have bought only lottery tickets on your site since I've started receiving those rewards.
I made a withdrawal with the minimum amount possible in order to check how it works. I'm happy to return it, just give me a bitcoin address and I'm going to send it back to you. This is not the amount I want to be blamed for.
I appreciate all the rewards you gave me so far.
Leaving this topic, wishing you everyone all the best.

I think Pierre 2 was about to say that he/she won't buy pizza and not that won't buy BTC. If he/she won't buy pizza for BTC that can justify his/her next sentence about the valuable BTC's he don't want to spend but hold.

My understanding and experience is a bit different. People are doing the easiest and most convinient things if possible. So if they are not forced to use bitcoin (TV spots, marketing, etc) only a few of them will realize the benefits and will start to use it because of his own inner motivation.
So as long as people think that BTC is for online casinos, gamers, etc, they won't think to use it as a kind of digital money nor currency at all.
If some big electronic chains will start a campaign to pay with bitcoin to get some kind of discounts, it could have some positive effect. But why any of these big chains would start accepting bitcoin if they are not able to spend them, to buy stock or pay salaries etc.
