As you'd already know, that there are limited number of bitcoins that actually exist. And all of it is not mined till now. What we all have is just the mined amount which is circulating. And as bitcoin has very very good advantages for people in trading business, like it's transactions are real fast and easy, time saving and many more. And now more and more investors are getting attracted towards it so all these factors make the price of bitcoin reach unprecedented heights!

The future of any altcoin depends on how good the peoject is and how well are the developers doing with it. If the project's motive, it's aim is really good and attracting but the team working on it is not that hardworking or just there to make some money then that kind of project doesn't really has a bright future. So, for the project to be a big hit and successful it needs both, an attracting motive and a really hardworking team. So that's what makes a good project, which has a future... Bright future.

The right time to cash out is when you and only you feel so. If you feel it right to cash out and you just want that particular amount of profit then it's the right time. And of course never cash out when the price falls below that price in which you purchased. And only cash out when the prices are high! Never panic if tge coin you're holding is showing a decrease in price, instead wait for it to rise again and then you can sell it. And if the price of that coin rises further, you should never feel that you took a wrong decision. It's trading, either you have a profit or loss nothing else and always focus that you earned profit, how much? Doesn't matters!
Good luck!

Myetherwallet
It's one of the best user friendly secure wallets for starters to store their ethereum.
It's advantages are-

• Secure
• Online wallet
• Easy to use
• No chance of getting hacked

But it has some disadvantages too

• Online wallet
• Private key if lost. Then you lose your eth.

Yes, it's an advantage and disadvantage both of myetherwallet that it's an online wallet because if theres no internet you can't access it. And if by any chance the site goes down then that's a problem too.
But overall it's well secured and you just have to keep the private key safely with you and only you!

Now is the time to sell half of your bitcoin and hold the rest for the future! Even if the price never falls you'd still have a good amount left with you. So I'd suggest that hold half of your coins and you can sell the rest if you wanr. And if in the coming future bitcoins value drops buy the amount yiu sold again or maybe invest the profit you'll get after selling it now too. That'll be juat pure business. So you can take most out of bitcoins!
It's upto you that you want to take risks and sell half and wait for the price to drop again to rebuy it. Or you can just hold it for more time, that'll be really long time. So good luck!!

If you're talking about bitcoins then holding is the best option that will make you a good profit and you can make the most out of it. As the price of bitcoin during these days is really rising like anything and it is estimated that it'll further keep rising in the coming years which is a really good reason for holding it and be greedy! And if one plans to hold it then he should have a secure wallet to hold it, otherwise there are high chances that the wallet might get hacked and all your money might just vanish as there is no way to get those bitcoins back!
But if we talk about altcoins, day trading is the best for you if you have ample of time and are ready to do some work!! But if one doesn't has a lot of time that they can be updated from time to time then theres no harm in holding those coins but not for a long period of time instead hold it for 2 to 3 days and that might work too!!
All the best!!

If theres trading theres loss. So before entering trading one should always be prepared for the loss which might come in the way. If i have a loss i don't whine about it, i start making plans on how can i compensate for the previous loss. I go back to the start and try to figure out where was my mistake that i invested in that project and had a loss then when i know it, i try to learn from it and keep that in mind so that i don't repeat it again. And learning from our own mistakes is really helpful in any career.
So, Learn from your mistakes, and just be brave and think of ways to make profit in the future!!!

You save a lot of time when you use bitcoin. Trading is really easy using bitcoin. And in the past few days the price has shown like a really
really fast growth in it's value. So you can conclude yourself whether it has a future or not. Oh sorry A bright future or not. It is attracting more and more people by it's rapid raising prices. With all the advantages it gives, it just seems that it is only the currency of the future. More and more people are starting to gain information and are willing to invest in bitcoin. And why should they not, it's always a good time to start believing in bitcoin and gain profits!
So yes. Bitcoin does has a really good future, until there's electricity and internet. Otherwise, well no electricity, no bitcoin.

There are a lot of advantages if you have a stable job. If you have a job that allows you to keep a check on the market and trade side by side then that's perfect and you really should continue that. But if you have a hectic job which doesn't give you time for some extra activity then it is preferred you stick to your job. But if you really want to do trading then try doing it when you have your holidays and see if you can fit in that profession and make some good profits. Try that for a while and then when you feel that you are wasting your time in doing a regular job and you can do great in trading. Quit the job. And start trading.

But trust me trading is not for everyone, so just give it a try in the start and if you feel you fit in, then only continue.

Etherdelta is well secured and really easy to use. The user interface it provides is just speechless, which makes it more attractive to use. I like to use etherdelta as it is safe for all the transactions i make and the transactions are fast and easy to track. There is an instant report of the transaction when it is completed and the ETH is also safe there.
So, mainly it's the best because of the following points-

• User friendly
• Secure
• Good user interface
• Instant transactions and easy to track

There are many investors out there who strongly believe and have faith in the cryptocurrency and also believe that it's a revolutionary technology and the technology of the future and cryptocurrency are the future money. So they definitely do buy these COINS with REAL MONEY. And there are some people who trade things with crypto coins and i think that is a very great exchange. As there is a fixed price to things. But the value of coin is not fixed, which is a bit risky, but still if you accept a good coin and hold it for  some time then chances are that you'll make a good profit!

I don't buy altcoins i just join their airdrops. Its the best way to prevent loss. It clearly takes and consumes a lot of time but the risks are like, nothing. You don't invest anything and you can hold a new coin. And when you feel like this coin might be a success then you can think of buying more. And if that coin does not do well enough then you can just sell it and have at least something with you. So personally i don't prefer buying a new altcoin as i can't invest the time required for researching about it and the risks are also too high. So i just prefer airdrops rather than buying.

I don't buy altcoins. I just participate in the airdrops and get as much new altcoin as possible. Then if the price of the altcoin rises i usually sell them. And if there is a fall in the value i just hold it for a longer period of time and hope for it's rise. And then sell within a week if it's a rise or sell.
So in the complete process i have only profits. Nothing else. As all the coins i got were free. And still i made something out of nothing. 

There is no such thing as choosing a good coin. It's all about your luck. It's just unpredictable.
First to invest in a coin you have to spend a lot of time in researching about the coin and then analyze all the information collected. There might come losses in your way even if you research a lot. Because the success of a coin is not in your hands.
But you already know a great coin. Bitcoin. You can invest now and it's price will just keep rising!
Bitcoin is just the best, to invest. All others are risky.

If you're asking about bitcoins, i usually sell them when i see a profit like say 10-30%. A time like now, where the price has risen up to $9,799. And i bought some btc like two to three weeks ago on 13th November to be precise, and it's value then was around $6,500. So now i am planning to sell my bitcoins and I'll buy it again when the price drops. This is a really good way for at least me to earn profits and the profits i earn i invest half of them in buying more btc. So i usually hold for a little time and sell whenever i see 10-30% profit.

I personally rely on campaigns of different types to increase my btc. There are a lot of campaigns like signature campaigns, Facebook campaigns, twitter campaigns and the list goes on. But the best campaign among all is, i feel signature campaigns. It's the best way to earn btc and do some actual job by posting a certain Number of posts per week. And then get rewarded for it. The other campaigns are basically equivalent to copy and paste and promotion of that project through copy and paste, whereas signature campaigns requires some effort of writing.
So, Campaigns are a way to increase your bitcoin.

There was a news about confido recently. That it's team have abandoned the project and disappeared in the dark with all the collected money which they got from investors.
No doubt it SOUNDS a good, in fact great project to invest in. That's why it was able to collect about $375,000. But at last it came out to be a spam and nothing else.
We should always keep our eyes open and stay safe from such projects and prevent our loss. I really think that there should be a decentralised platform to certify genuine project and have a check on the progress and work of these projects.

As new projects will keep on launching the demand for ethereum will keep on rising, which is a really good reason to invest in ethereum and start gaining profit from it. But currently the price of ethereum is rising, so we can wait for some time when there's a drop in it's price and then invest in it. It'll surely rise again, All thanks to the new ICO'S that keep coming up and increase ethereums value and help in making it's future bright!
The bottom line is ethereum is probably the best altcoin out there and it has a bright and rising future and maybe
someday it MIGHT compete with bitcoin or even be Better than bitcoin.MAYBE.

There are no doubt some ICO with no work at all they just have some fake promises with them and fool the investors and public and collect all the money.
There should definitely be some kind of decentralized platform that regulates all the ICO.
And the people too must always think a lot and research each and everything about the project before putting in any money in it.

If you're storing bitcoin for a long time, then make sure you do have a  really good and well secured wallet or the chances are that your wallet might get hacked and all your coins might be robbed from you. And other than that, there is no other threat that might harm you or your bitcoins. As it's started by "SATOSHI NAKAMOTO" who is a MYSTERY. And if anyone ever tries to kill bitcoin, they might have to solve a mystery and then get him or them then interrogate with them and so on. But even if all that happens bitcoins is used by millions now, so it might just get circulated and it'll never die.
The bottom line is, have a really secured wallet to store you bitcoin for a long time.
