You are right in saying some smaller charities doing some practical things to help people. I would like to donate to them if the money is spent frugally. But there are also many small charities were set up to swindle  people's money. There are news about this kind of scandals every months. The problem is to find the right charity.

That is a very good reason to pay porn website service with bitcoin. However, in the future, even if the bitcoin is regulated by the government, you are paid salary with bitcoin, it is still good idea to pay porno with bitcoin, because it is semi anonymous. There is no possibility for credit card processors to reveal your identity.

Gambling is like many other methods to get fun and pass time. People spend time and money to watch film, go to theatre, travel around the world and many other activities. Gambling is to spend and money, wit very little chance of getting the money back. But in the gambling process, there is some fun.

I heard some charity staff travel in first class air plane seat, stay in 5 start hotel. I do not travel like that and try to save every penny in economy class and non 5 star hotels. Some executives are paid hundreds of thousands dollars per year, I do not get paid that high. Why should I pay for their high living standard?

I would like to join.

Everybody is responsible for his own action. We will just say that if somebody gamble with all his possessions, and lose it all, it is quite devastating. If he just gamble with small amount of money, there is no problem to gamble at all. Gambling is for fun if it is done properly.

This is true to some extent. With investing, you can do some research on the company or sector you want to invest. Gambling is mainly based on luckiness, within built in house edge against you. In long term, the investment in stock market in general is positive. In gambling, it is negative return.

I will donate bitcion only for the purpose of promoting bitcoin and for the goodness of the charity. If a charity does not accept a bitcoin because bitcoin are not in the good books, I will not donate the bitcoin and neither the fiat. It is their loss. I put my bitcoin into other good uses.

For some people, there is no greedy involved in the gambling. They are playing just for fun. It is a way to pass time. They would be happy if they win, if they lose, they will not be too said. It is just like buy a service with money to pass time. It is not necessary to involve greed.

There is unlimited number of fiat can be issued to cause inflation. The number of bitcoin is limted. So bitcoin is widely accepted as a currency, the price appreciation is unlimited. It all depends on the continuous development of bitcion. The latest catalyst for price rise is the agreement of block size increase.

Gambling is for fun. So if you just spend  a little amount of money  and are satisfied with small amounts of winnings, gambling is actually very fun. If you want to be very rich quickly and bet big, you might lose big, gambling becomes a distressed experience. It is better to know when to stop.

$450 in 2016 is very possible. I even think bitcoin will finish above $450 in 2015.The bitcoin price is seasawing below $400. It is a kind of consolidation after the recent dramatic rise. It is preparing for the next push to higher price. More news about blockchain technology adoption will give the price a lift.

Gamblers are essential part of gambling industry. They provide funding to the industry by losing in the gambling process. There will be some winners, but majority of them will lose money to provide jobs in the industry and pay tax to the governments to support the whole society. Gamblers pay more tax than ordinary people.

There is no difference between casino (gambling) and other service industry. There is no request for filming, cinema, and club, to donate their earnings.
Gambling industry  provides job opportunities to the society, they already pay large amount of tax and contribute to  whole society.
We do not have the rights to ask them to donate funds to charity. The government should use the tax from gambling industry properly.

Great match skills are important. A good memory is also very important. If you can remember all the cards in  Balckjack, and analyze the situation  properly, when you have bad luck, lose small, when you have good luck, win big. You can win the game in long term.
However, not many of us have this skill.

So from what I understand from your post, you are making 8 bitcoins per week. That is a large amount of money, or about 400 bitcoin per year. Not many professionals can achieve that. Hope you harvest fun as well as money.
Can I ask what sports do you gamble, what is your winning strategy? I do not mid if you do not tell me.

To Ebay, there is no difference between bitcoin and fiat. It can recover bitcoin from a user if it wishes. If you owe bitcoin to Ebay, and you refuse to pay volunteerly, Ebay can get a debt administror to chase you. If we pay the bitcoin through Ebay, it will also get our bitcoin back if the seller does not deliver the goods. It can also hold the bitcoin on seller's behalf for certain period to protect buyer.

We need films mainly about bitcoins. But we also need many films to show that the characters in the film mention about bitcoins or they can use bitcoin to purchase a cup of coffee in a local shop or do on line shopping with bitcoin. These kind of scenes can be shown in many films. So the advertisement can reach more people.

In investment, you have paper loss or gain as soon as you buy a share. It will not turn into a actual loss or gain until you sell your share. To that extent, it is similar to gambling, you know the gain or loss instantly. Share investment is for the long term, while gambling is for the short term, some times, second later result.

Although less than 1% of bitcon users are making coins from signature campaigns, more that 1% post in this forum are posted by campaigners. The percentage could even reach 10%. If you count the post in this thread, more than 30% are posted by campaigners.
Signature campaign is effective. That is why there are so many bitcoin casinos advertise here.
