There are also decentralized platforms like localbitcoins, bitcoin.de and Mycelium Local Trader. Or you could spend your bitcoin on goods and services directly using Gyft, purse.io and numerous bitcoin accepting merchants.

Nothing really happened AFAIK. Someone was sending out phishing emails trying to scam purse.io users, purse.io noticed the phishing attempt and sent out emails to warn its users. And as always, you should enable 2FA and should never click links in emails (including those seemingly real ones).

I guess were some kind of joke saying bitcoin isnt money,anyway,gambling isnt a bad but isnt a good thing to do with precious bitcoins.

Its depend of your winning. If you lose its wrong, and if you win its not wrong lol. nah, i think gambling its not wrong, why wrong ? it's can make you easy earn money and easy lose money. so be wise about gambling.

can you provide more details regarding to other tools to make bitcoin online. that's quite interesting, i'd love to earn without any risk

Poker !! do you mean casino poker or multiplayer poker ??
multi player poker is a beatable game and you can make money from it more than a sportsbettor , yes the site makes money cause they take rake but this doesn't mean that players will always lose their money
the site is for sure winner but also good players are sure winners

There is many methods like mining, trading (if you have good experience in this ), and even sig campaigns, you can also sell your goods or services online.
at least in this tools -except trading sometimes- you can't lose all your bitcoin, you can only without any risk.

When you gamble, Make your own rules, and FOLLOW them strictly. 

I have a lot of rules when I gamble, I have "fun" money whether it be bitcoin or cash.  I don't ever lose more than that what I had set aside for the fun money.

Also-know when to quit when you are ahead, I don't ever set a goal for how much I want to be up, because if you are so close to that amount, you might never hit it and then be out of money.  Usually depends on the situation, but if I hit a couple lucky runs, I will say, ok, I am going to be up this amount no matter what, and replace my fun money with profits, so that even if I lose, I still maintain my profit.

Use gambling as a time for fun, don't try to get rich out of it.

Agreed.
Better mining than gambling.
But when you choose to gambling.. "Make your own rules, and FOLLOW them strictly."
Nice quote leex1528

currently mining isnt for all pockets ,if bitcoin price raises a lot of old miners would return into the process,gamblin will lead into a loss in a short time,soo better invest or trade bitcoins,but well investments arent 100% safe otherwise a huge ammount of bitcoins would be at just one place already.
