i am sure if you think about it, you will realize the difference and how big it is.

for example when you flip a coin, can you say if it will be heads or tails? obviously not. there is the same 50-50 chance and you have no way of telling.
now when you trade, you can not say what the price will be after the period you have in mind, because you don't have a future machine. but instead you can analyze, this can be technical analysis on the charts, or analyzing the news and things that can affect the price and 1000 other things and come up with the most possible scenario. and be more than 90% sure about what is going to happen and make your move.

also the other big difference is how much you lose on a bad move.
in gambling if you bet on heads and you see tails you lose all.
in trading if you speculate a rise and price goes down, you sell at a loss and lose a small portion.

you can use any strategy that you like or feel that it gives you better results but in general martingale strategy is best for games that are not skill based games. that is why you see this strategy mostly be used in dice games.
when making bets on sports you should be able to make bets based on your information about the team and know which team is going to win or which result is going to happen and make bet and win each bet or at least majority of them. if you are losing most of them, then you are doing something wrong.

what volume increase are you talking about, i don't see much change.
it is the same thing as any other pump and dumps, when price is going up or down, volume increases, nothing strange because traders are dumping at both change either to make profit or get out and save on losses.
the volume increase that can lead to rise is when price is stable and they start accumulating, hence increasing the volume before the pump comes. and i don't see that here.

run litecoin core if you can and want it, because full nodes is always best thing you can hope for, in sense of privacy, security, helping the network and many other things.
if not run Electrum-ltc which is the SPV version of litecoin wallet which means it doesn't take much space and is reliable enough, you can make a cold storage with it also.

for exchange you can use many that offer it, poloniex, bittrex, btc-e, are the top in my opinion.

well automobile didn't put horses out of business the first day it came out, it was first a big thing that needed to be started with a turning of a handle in front of the car and it was a slow vehicle at first. the same as any other technology it takes time to become more advanced and get adopted.

and the least thing we can expect is the extinction of the current form of fiat.

you can not escape from income tax using bitcoin, the IRS will come hunting you down if you do so. you are earning your income from somewhere and you have to report it, using bitcoin can not hide that.

i agree with your speculation for the most but but i think it is still possible to see lower prices such as below $850 because in the past things like this happened a lot and they are mostly for testing the bottom resistance and cheap coins but i do not think going below $850 means $780-800 is possible.

you are not saying anything about the strategy and yet expect us to help you!
but from the little information you give about two mobile,... i think you are making a big mistakes in your calculations in your strategy because using different devices is not going to change anything about your strategy or give you any edge.
unless of course you are exploiting some buy with this technique, in that case you will be blocked and your money gone. and it is illegal too.

they obviously each have their own wallets, but their wallets are always going to be Full Nodes wallets which means you have to keep a copy of their blockchain if you want to use them as wallet and that takes an unnecessary wasted space on my HDD so i never do that.

instead i keep them on the exchange service that i use and i realize the risks involved but there is no other solution.

however there are some SPV wallets such as LTC-Electrum that i am using to keep my litecoins and it is light wallet so it doesn't keep much space.

it is because you saw the result of the rise not from the start.
if you were a trader and checking the price every minute you could clearly see the price rise starting from lower $800 to $850 and then by the mid day it was $880 and finally the price you saw the $900

anyways it was a nice rise and good test showing market is ready for the rise and it was a good short term opportunity to make some profit for the next accumulation phase.

he is suffering from a serious case of trolling and also multiple personality disorder which you can clearly see in his post history

and litecoin is not at all dead or even dying, it is being developed actively more than 90% of other altcoins out there. it has recently added support for SegWit and miners are starting to signal adopting it. it is moving forwards and also as i always say Chinese are very interested in pumping this coin from time to time, and when they do they pump it big.

i am not going to tell you what to do but instead i am going to tell you what i think.

bitcoin is a sure thing, when you invest in it you know that the chances of you regretting that investment, specially in long term is very slim and nearly zero.

but ethereum is an altcoin which is a very risky investment. it has many downsides and many problems, which means price of it can not go up with adoption. however it is manipulated, which means it can get pump and dumped and you can make profit from the pumps if you can catch them and lost money if you are late and get dumped on.

you need to be more specific with your question.
generally speaking casino bonuses aren't based on luck but they have a certain, completely clear set of rules for you to claim them and then another set of clear rules for you to be able to withdraw them.
for example to claim them you have to deposit a set amount of bitcoin e.g. deposit 1BTC get 1BTC
and most of the time to be able to withdraw that bonus you need to make a certain amount of bets e.g. make 1 million bets.
and these change from casino to casino and from bonus to bonus, the easiest way is to read the FAQ of that casino or ask the support.

you forgot to ask what kind of game you are looking for, there are many online casinos each offering different game or range of games to play.
there is dice, roulette, coin flip, .... card games such as poker,.... sports betting, esports betting, betting on weird things like result of an election,....
and each of these have at least a dozen good sites. you can also search the gambling board to see all of them and choose one based on their topic and user's feedback.

the strategy that i use mostly depends on the game that i am playing, and in most games i have no strategy because they are not strategy compatible.
but for dice games, which are my favorite type of games, i made  a topic about the strategies used and it has a couple of good replies in the topic too. you can see it here: https://bitcointalk.org/index.php?topic=1720702.0

so far it has been similar to 2012 and early 2013 when everyone was running around making new topics saying price will not go above $10-$20 and we will go down and then price went to $1000 and they all were silenced.
now we are again on the verge of either a huge rise or at the very least follow up on the slow rise from 2 years ago.

these two are irrelevant! you can even say they are the two most irrelevant coins.
what i think is that you are wrong about bitcoin price, and XRP is the same as always it goes up and down, maybe 790 satoshi was a bit of a high price to buy at specially today that price went down to 750 satoshi but in long term it tends to come back up but you may have to hold it for a long time.

fist order of business is to come up with a new game for the gambling site. and that is the hard part because the game has to be new, and it has to be good enough that players want to gamble. if you start the same casino as others, you fail right there, if you have a boring game, you fail again.

then the casino has to be as transparent as possible. this can be with their funds, their provably fair system and trust they build up.

and finally it is advertisement. which i think we all know how to do. it only needs funds and consistency (not advertising for one month and give up)

well, in sports betting all you need is that you should be a fan of that sport game or in my case be a fan of that e-sport game. because being a fan means you have lots of information about the game and the team, and having that is all you need to be successful in betting on sports, and we are all looking for fun and profit in gambling and once again being a fan satisfies both of these.

my vote is still bitsler.com

they have been performing very well, with a very good and fast responsive support with active mods on the site.

and not to mention the fastest rolling speed that i have ever seen in all the dice sites out there.
