According to me i think that the answer is "it depends". It depends if we looking for short-middle-long time. For example in short time bitcoin is a very bad choice because if his price go 100$ upper, it represent a little increase globaly. Bitcoin explain own best face on middle and long time but you would be able to change the trend if another blockchain take part on the ecosystem significantly. Furthermore i think that network effect and age bring bitcoin to the highest level of resiliency. Lastly, i think that the best coin to invest is the next.

I guess like 99% of people doing this business shares the same feeling with you. This is in the nature of this business and at some point we all do the same so called 'mistake' and sell stuff early. Or even sell late sometime. This is something we can learn from. Patience is the key if you really trust a coin.
Also sometimes we could be in a need of cash and we sell our precious coins as soon as they increase. All these stuff happens and we can't do anything.

Yeah the most important thing before investing into an altcoin is just look into their team, their developers, the community, etc, there are a lot of things that anyone needs to know before investing into an altcoin/ico, it is so difficult for me to have trust in a new project, but sometimes i like them and i believe in their roadmap over all things.  But it always depends, so in top altcoins you only have to look at the charts.

since ethereum additionally has some genuine scaling issues and each time the quantity of exchanges on the ether chain increments, everything goes to hellfire. the cost of an exchange will increment too quick and too high, significantly quicker than bitcoin and you will feel the gradualness, and there additionally have been not kidding cases that the system went down and trades needed to debilitate store and withdrawals for seven days until the point when the issue was understood.

this for the most part occurs amid the ICOs where there is a great deal of disorder happening all over the place.

ADA and cardano is not a bad pick, but you would be better off going for Ethereum if long term is what you are seeking. Ethereum has all the fudamentals and the making of a world changing project. Even today i'll let you do it yourself and you will see that if you take your time and really look into what ETH is built and designed to do, you would be amazed and immediately buy Ethereum.

FYI, newcomers!
Did you know you can mine NXT (and buy Ardor with it on the Nxt Asset Exchange!) in the Lucky node project?
Computational and bandwidth requirements are very low - some users run it on a Raspberry Pi.
Run the node 24/7 or as often as you can while you work or play.
Join in with the over 100 nodes that are already in the project.

Guys, can you share with your statistics of air drops? If it is possible, can you provide numbers? How much did you get from air drops (in USD for example) ? Which air drops?
I have never taken a part in air drop campaigns, so I want to know if it is worthy to join such campaigns and to spend time on it. As I see there are lots of topics about such coins that is why I become interested in them so much. The main thing I know according to your posts is that you do not need to hold such coins, it is better to sell them instantly. Am I right?
Thank you in advance

If bitcoin has not eliminated its shortcomings for a long time, it is quite possible that in the long term, and not next year, Ethereum could well become a contender for the place of the leader of the crypto currency. However, soon a network of lightning will be introduced into bitcoin, which is designed to eliminate the existing shortcomings of bitcoin, namely, its slowness and high transaction costs. If this happens, and bitcoin will lose its current shortcomings, for which it is now heavily criticized, then Ethereum will not have a chance to bypass bitcoin.

Don’t worry the whole community think in the same way as you are thinking right now. No one is going to support BCH in middle of no where when it just got pumped to double the initial prices. I mean that is clear cut pumped price and market cap which can not last forever and big plays in the crypto field knows that very well. People will not fall for this today and you will see the hard fall in BCH price in couple of days surely. Im pretty sure those getting into BCH at this point will loose hard so better decision is to stay in the bitcoin blockchian and wait for its hard pump again. The golden period is here and yet you are no where. Come on guys stop the non sense of supporting the BHC. lol.

Why are You people complainig about Your loses, market price, exchange, ignis coin etc ... Guys ! did someone told You or gave You a quarantee that Ignis will hit 20$ or NXT will keep it's value ?
Are You first time investing Your money ? Spend some time to study the chart and get Your own conclusions - IGNIS is barely after ICO, so it have to prove its value, by showing roadmap, etc.
Patience is a key !!

 dont think so it able to defeat bitcoin. the reason is there is a lot altcoin that providing better services than bitcoin but still cant compete with bitcoin. for example xlm . xlm got a cheaper fee and faster transaction yet still far away from bitcoin. i dont know what kind services that will be provided by this project that you mention. but i believe there is no way it defeat the bitcoin. if its true bitcoin will be defeated it would be by top 100 in coinmarketcap

Litecoin is Bitcoin made right.
No premine, unlike Bitcoin with Satoshi millions.
Fair launch, no ICO bullshit, even Charlee Lee has to buy his litecoins.
Made by real developer: MIT graduate, former google engineer, probably most competent developer in crypto space. Unlike bitcoin with magical "best programmers in the world" core team.
Real non anonymous founder you can talk to.
No Segwit drama, no transactions problem.
It just works.

I believe both DAG currencies - IOTA and Byteball have great future ahead. Specifically for IOTA - Internet of things is picking up and number of connected devices would go into billions - this is one of the fastest growing markets also for company where I work. Due to number of devices connected and number of transactions that would need to be processed, the traditional blockchain based currencies are not suitable for this type of application, therefore IOTA, specifically designed for IoT transactions would be growing together with this market. It does not replace the blockchain currencies but it acts as supplementation to these blockchain networks. 

 dont know why this is giving you headache. we all know that XRP price is being manipulated. not only XRP but also other cryptocurrency especially the altcoin token. many of them are tipped off. that shows technically that some dev probably those that have highest percentage distribution might influence the price of any coin if they want to. It is XRP turn now so if you buy xrp when it price is low then enjoy the pump while the offer last. but remember nother last forever

Just wait for a few day before you sell you alt. The best move right now is to monitor the price gap depreciation before you decide to sell your alt. If you see the value of your alt is continuously decreasing i think it's time to decide but think of it before you do sell and calculate first if your profit and investment not loss. If you think you continuously losing your profit and capital i think its time you to decide if have no chance to increase the value of your alt. But if you feel that have a chance to increase again the value of your alt, why you don't try to hold your alt to gain profit simultaneously.

It depends on the coin you are in. Most airdrop are from shit coins trying to get a quick buck in etherdelta, but fortunately there are legit ones. You just have to DYOR to decide whether to hold or not. There have been a number of XXX coin ETH version of coins going out lately and obviously they're all shit coins (Etherreum Dark, Blue really??), but there are also legit ones like DeepOnion. They are on round 16 out of 40 and the airdrop rules have changed so far to help accomodate new entrants. The previous system for airdrop participants requires around 10 posts/ week to help promote the coin but right now it was dropped to 5, and the application process was re-worked so that it's easier to join. It's a pretty good coin with a large and solid community, great developers and user interaction and most of all an outstanding product. It's geared towards privacy (which is a must in today's government tracking efforts) and a whole lot mroe of features for a secure transaction in the blockchain. I suggest you check them out and decide for yourself. I'm personally rooting for them to be one of the top tier coins in the privacy sector in the years to come.

Currently I haven't bought any single altcoin yet because I do not have the fund and capacity to do it right now so I am collecting funds first by joining promotional campaign in ICOs. Once I have enough fund then I will do trading and I will buy altcoins as investments. Bitcoin is the primary cryptocurrency now but I personally believe that altcoin is a good investment. There are may good altcoins listed in exchanges with good performances in the blockchain and are worth investing. Etherium coins I believe are good crypto and are mostlt bought if I am not mistaken.

computer hacker might works with their strategy as spreading script with the function as copying extract of initial type of files to work as running as the beginning of attachment of usb stick to the port of cpu,
as the additional function might be of one as capturing the text file type (notepad,dll) and push with the request to connects to ftp server with the hosting of script as uploading files and becoming publish in internet with the selection of order commands as those might be of one with the different option of ftp upload from the script switches hosted with the server, with the http request to call from the hosted script or more with the different function from library as establishing connection through the different arrange of lines from the non web base script hosted with the online server.

OP your post become constructive because it's positive in many ways like if they read this they do investing here too and i think you don't intentionally did that but your happy that's why you post like this,Moreover i think also it's good to invest here but always think that you can lose also and for more good do invest in trusted coins already like btc,eth,xrp and xrb for no losing at all another thing this coins continue to grow you need only to wait for profit and don't nervous then sell it in high price when the time is already come.

t depends on how much you want to risk and how big profit you expect. Bigger risk equals bigger possible profit.
Keeping ETH is probably much less risky than buying some altcoins, but the short-term profit is also quite limited. Buying alts can bring you much bigger short term profit, but is also much more risky.
As always, it's your money so it's up to you to do the research and decide
