Gambling is a sin in many religions. Their argument is that you cannot predict the future and only God can. In fact this is a bit of the truth,  you can only try your luck in gambling but you cannot predict the future. I wonder what has been going through the head of the persons who have won big jackpots from gambling and how many time did they play before hitting it

Didn't mean to promote them but just stating which service offers even lower odds than 2 in a parlay and ask monthly, quarterly, half year or yearly payment for that. Now I am editing that post to remove it. Martingale is not rekt if you have infinite bankroll, using odd 2 once in 50 bets you will one single bet with such odd. It is against mathematics and statistics probability if you don't win any.

Don't do lending on Poloniex although the profit may sound optimistic there has been a lot of complaints in this section of poloniex and some people didn't care and didn't pay back their debt. They didn't care at all that poloniex closed down their accounts. I think now this section in Poloniex is not that active anymore.
With that amount the best to do is buy and hold and is much better than any mining operation. Hashnest are legit but not profitable.

It depends on your electricity, if you live in Venezuela ,China or India even the oldest one the S5 Antminer which you can get for very cheap second hand through ebay can be profitable for you because of your low electricity payment.

Gtx 1080 can do about 400 M/Hash by mining Library coins and can go much higher than that when mining really low difficulty coins or coins who have just show up. You can't mine bitcoin with it but it can make you about 155 dollars per month with energy cost removed so there is net profit with this card 1080 ti 155 dollars per month. Having 2 or 3 of these cards can bring you the same result as having an antminer S9. The cost of such card is damn high though.

I think  the OP means not to invest in a casino bankroll. He is asking why you guys keep playing when the best will be you get 0% ROI or you lose your investment of bitcoins by playing with them. I play for fun also but my main concern is to make any profit. Unfortunately until now I am only losing to slot machines and I think I need to quit before I become addicted.

When you invest in a casino you get a cut of the profits of the casino.

This is true for the ASICS and S9 not going so well. You can make 0.012 btc a day through Nicehash miner with a PC that has 6 GPU-s of AMD RX 480 which is a very nice amount without deducting electricity fees but still a very good amount. Why should I tire myself configuring the Antminer S9 when I can point my GPU-s to the Nicehash miner and enjoy the profits for the moment. S11 is needed and I predict it will be around during August of this year.

It is online gambling due to many advantages it have against traditional gambling. When betting with bitcoin you get anonymity and you play from your home. In traditional gambling you have to go to a gambling house or to a neighbor bookie. Online gambling let's you enjoy your day better because you don't lose time going and coming to the land gambling house.

10 parlays starting from 100 for example first one 100, second one 200, third one 400 and so on until 51100 10th one. This is called martingaling the bets.

I am part of a service who charges me 9.99 pounds a month for odds sometimes lower than 2 in a parlay and it is the xxxx (removed for not promoting it here) service website.

I agree with you that this is not needed better to martingale single bets with odds 2-2.5 if you have the guts to do it.

For example if you start playing a parlay with 100 USD and then play 10 parlays with martingaling the system. This way you need 51100 USD in total for the 10 bets.
Assuming you play only parlays of odds 2 to 2.5 it is proven that one in 10 parlays especially from professional punters will be hit for sure. If you hit the 10 bet then it is 51100 x 2 with odd parlay you win 102200 USD or 51100 USD pure profit.
Betadvisor is one of these websites where you have all the professional punters verified. This can be done also with a single bet of odds 2 and martingaling until you hit one.

Extremely dangerous yes, but many people have changed their lives from this strategy and many more ruined their lives also following this strategy without guides and websites like Betadvisor.

My personal advice is to not try this at home to anyone here but what I wanted to prove is this can be done only from professionals.

I agree with you 85% but if I find a good punter site which is truly run by professionals I prefer to wait until we hit that 10 leg parlay rather than playing single games every time. It is just a different opinion on the matter. The conclusion is I also believe more parlays are lost than are won but I prefer to hit that 10 leg parlay with bigger odds by hedging all the times. It is a risk I am willing to take because of the higher reward when it will be hit.

This is not the real truth. This is about 85% of the truth. The other 15% which usually are professional punters will tell you that no matter if you have a lot of lost parlays before hitting a 10 or 20 games parlay win, this win if bet with the appropriate amount usually martingaling the bet after each loss will result in a huge win. I agree with this truth only up to 85%.
I am just starting out to read a lot of sport betting and I also registered in some premiumtipping service in this forum. I am happy with their result so far.

International games when they are friendly are not hard to predict. For today I have in mind a game which has finished last time 1-1. I am talking about Albania vs Bosnia Herzegovina and I think today too we might see a both teams to score again in this game.

I guess the OP wants to say that in some games your referral plays you get 5% commission and in some other games you receive 10% commission. If affiliate payments are a lottery all people will stay away from this casino house.

Many wallet providers are already being prepared if the hard fork happens so the gambling houses should do the same and tag along with these wallets. They should keep a hot wallet with few funds and the majority in cold storage like they already do. I don't think the hard fork will impact bitcoin gambling in general.

Gambling is like the dessert which they say needs to be eaten in the end of a meal. I play at night almost always because I have finished all my daily activities and chores and I want to have some fun and excitement and gambling is the best to give you instant emotions. The problem is not always these emotions are good, sometimes when you lose every day for a certain amount of days you don't feel emotions anymore but only sadness.

Hey it's been only a few days since I bought membership through Paypal at your website and I can say last 2 days were wins. Yesterday was a win too. I already made back my investment for the month and a bit of profit. I hope you guys keep rocking , I checked the history and before I joined you had a lot of lost bets so I hope this changes from now on, wanna see more greens than reds.

I don't feel shameful for being a gambler. People don't know I am a gambler as long as I am gambling with bitcoin. The only times when I go to a land casino is on friday or saturday night with friends or with my girlfriend to have fun playing poker , blackjack and roulette. The real gambling I only play with bitcoin so I have nothing to be shameful of.

Gambling in origin it is wrong. Gambling can make people greedy or make them think that they can fulfill their materialistic needs through it. I think it is wrong because gambling can lead a good person to being not a good one anymore, it can lead to forgetting family and friends, leave daily work and many other bad things. It is better to stay away from gambling.

You must believe a lot in the casino you are going to invest that they will be here for at least one or two years. If you are convinced about this investment then it will be good to invest a good amount of bitcoin in order to see any significant profit. The recommended minimum is 1 Bitcoin and you should calculate that you will make a minimum 10% ROI yearly.
