1000 BTC x 670 $ = 670 000 $. That is a lot of money, and personally I don't know anyone who have so much money, with bitcoins or with fiat. I agree with some people that someone who have so many coins, he would not go around and talk about it. He will instantly become target to some hackers, they just wait to catch someone with that amount of money.
But probably its not so simple with hacking this amount of coins, someone use some good wallet, and probably coins are offline.

Try first to follow coins, for that you need to choose few coins you like, take a look in history of that coin to see how was before with that coin. After that wrote on paper your predictions, and if you are close or you see you are on a good way you can start invest small amounts of money.
I repeat all the time, informations is something that worth a lot, with good information you can earn a lot of money, so try to inform yourself best you can and that is it.
There is no big magic in trading. I wish you to have a luck in beginning and to make some serious money with trading.

It have similarities, but its not the same. Even we can't compare gambling with trading cause there is so many games in gambling. Maybe we can compare some of the games, but for sure not all. How to compare dices or slots with trading?

Generally in both we can have luck and win a lot or we can lose a lot, people should be careful to not invest to much if they don't know what are they doing. Like in gambling, in trading you can lose everything in second if you play all in in wrong moment.

I think I have same results with trading like OP, I just didn't have that amount of money. I made less profit with my investments, and my losses are not so big, maybe 0.1 btc.
I don't think I will stop trading ever, its nice fun and I like to watch prices go up and down. When I hear some good information about some alt coin I will definitely try to buy some little amount and try to make some profit.

People can make money with trading, only thing you need is good source of informations. With that you can make a lot of profit, but it requires good money for investment and patience for waiting coin to rise.

I had same experience at Yobit like OP did, many times I tried to gamble with some coins I gathered there and I lost everything. I can't remember which coin exactly, it was long time ago, but I had like 500 or more some shit coin and on dices I lose everything, and I thought its easier to make more coins with alt coins, what a mistake.
Better gamble on prime dice or some other dice sites, you cam catch some promotions, or giveaways at least, on Yobit you can just lose any coin on dices.

Slots are great game , maybe its hard to get something, but when you do you get a lot. Of course for that you need to have huge bankroll, and to rise bets always when you don't get something good.
I like slot games, I even opened a thread here in gambling section. I have few favorite ones, greedy goblins is the best, when you hit some bonus and have luck you can win hundred dollars in one hand. Of course if you play with high stakes.
Anyway stay away from slots if you are not ready to lose money, cause you can have luck in slots but not all the time.

Should? Well for sure they will have more customers there, for example I never bought anything there, I'm just downloading free things. If they accept bitcoins as payment they will have more customers for sure, and there is big probability for many people to skip to btc from fiat.
I think this would be great thing for btc, but I didn't heard nothing about this matter. Even if they ate thinking about it, nobody knows nothing. They are very secret about it, cause Inever heard they are interested in crypto currencies.

Can you imagine they start to accept some other coin, like eth or dash, or some new one? Can that be badfor btc? Or it will make btc grow?

I think some people think about bitcointalk forum like place where someone is giving away bitcoins, and all they need to do is come here register and make a first thread : " Hey I'm here, where are my bitcoins, and my money?" It's not one or two threads, there are like million newbie threads about getting free coins, and they didn't try a bit to find answers around the forum.

Everyone of us is working for money, no matter which currency, and there is no free money. For everything we need to do something, or say something, or make something, depends in what are we good, and what kind of skills we have. This forum is same,here you need to have constructive comments, on English ( for some campaigns its not matter ), and you apply for it and if they accept you, they will pay you for your comments.

Same thing I do when I win. I don't make a big difference between winning and losing, cause I don't put big money in casino. I get a little disappointed when from little I make a lot and like a fool I lose everything cause I thought I can make even more. But that is something that happened to me many times, and I'm still learning how to stop and run away when I'm in good plus.
Gambling is a game of nerves, so keep your nerves cool when you win or lose and you will have more chances for success.

Well currency is good as long we can use it for different things that we need. Coins need to circulate at the moment, how else to make market to grow? We need to use our coins, normally not all, but some part for sure.
How people imagine bitcoin to grow, shops and site's to accept bitcoins if everyone keep coins in their wallets?
Maybe exactly cause of this keeping we will see some other alt coin to rise in near future.

Everything is good, except headline. Its not nowadays, its something that has been preparing for years, and I just comment one guy that said " bitcoin hasn't reached full potential yet", here is my opinion the same. Bitcoin have power now, but its just the beginning of something amazing.

I think we can expect something big to happen soon, many people have same opinion as I do. Maybe we are right, time will tell, I expect things to start around October.

OP is right that bitcoin didn't reach full potential yet.But for sure we see stable price now, and until new year we can expect higher price, cause we still didn't see real effects of this halving.
October and November are months when I expect some significant rise of price. Before that price will go up slowly.
I'm glad that someone said something nice about bitcoins, I have feeling that we see to many trol threadz recently.

Prediction for next 5 years are good in my opinion, we can see more people joining and better adoption in online shops and store's. With that we can see price is going up, and probably we will see some countries recognising bitcoin as currency, and with that some laws about it.
Obstacles fot bitcoin, except some other alt coins, can be bank sector, or some corporation, maybe some rich person. But that is big question, what will happen and how. For now btc have a stable grow and I think that trend will continue in next five years.

In your case it sounds like you found it, and who found it can keep it! But that doesn't mean that you can't try to find the real owner and return coins. Stealing is when you take something from someone, no matter what, and that is not nice thing to do.
Finding things like money or something that worth is just luck. But like someone said, chances to find wallet with money inside is like you are waiting money to fall from the sky. Almost impossible!

I would play poker with 100 $. And with that amount you can try cash game more then once, even poker tournaments are great. Play tournaments that have low buy in like 1 $ - 5 $ and then you can even rebuy few times if you lose in first try.
Second game I would play with 100 $ is Caribbean poker, great game with good odd`s. But you can play classic martingale, try few times on same bet, then rise a bit and like that, if you rise double every next bet you will get in all in situation fast.
Third game is slots, but that is tricky. I think you need to have some knowledge about it before you sit to play this, if you are not careful you can lose everything. Play on minimum bet, and from time to time rise your bet. If you are lucky you will hit some bonus on high bet.

I don`t think bitcoin is getting in any crisis, especially not economic crisis. Fiat is different thing, there is someone who print money like crazy ( federal institution ). Then that money goes on credit to banks, and then banks give that money on credit to people or companies, or to governments. Everyone who wish to learn about fiat money can do it on internet, there is like million information`s about it.
Bitcoin is different, there will be 21 million coins, and that is it. When miner solve block he get a reward, now that reward is 12.5 after halving. So that is it, there is no institution behind it.

Physical casinos have more high rollers then online casinos, that is like 100 % true in my opinion. Can you just imagine some big complex hotel, casino.. they have private rooms for serious players. I just heard what casinos do for this kind of players, free rooms, beautiful girls around, something that online casino can never give to players.
Rich people, but really rich people will always choose physical casino instead of online. And I don't think situation will change, even I wish to go to real casino and play there. But I don't have enough money for that, cause of that btc gambling is something best for me.

In my country this is not possible, probably in some other more advanced countries this can be possible. For me drugs are like any other goods, people buy it for low selling for high. One day everywhere will be possible to buy drugs for bitcoins, that is the future like with any other currency, I don't see what is strange in this.
I can say I envy a bit to people who can do this, first time I can I will do it. Until then I will watch and listen how other people do it.

10 % in my opinion, no more then that, even less maybe. But who can answer on this question?

I believe we will see some threats to bitcoin, and people who predict right when will this happen and which coin can be that will earn a lot of money. It's open market, many things can happen. Maybe bitcoin will be strong and stable enough one day, and nothing can influence on that, but we can't say that with 100 % certainty.

Of course its possible, like its possible to remember all card in black jack, or all numbers in roulette. That can make your game much better, if you can memorize or previous results.
But I read about it, and every hand in gambling is independent from previous ones. That mean it doesn't matter how good you can memorize previous bets, result can always be surprise.
From reading other people experiences in gambling, I think more luck and profit make people who bet on surprises and people who chase higher odd`s.
