I agree that this coin is very likely to provide short-term profit at least because of it being legit and extremely popular among investors. Moreover, there's even a signature campaign dedicated to this coin right now! As for long-term perspective.. the project sound totally awesome but we don't know whether the realization will be on an appropriate level and whether it's even possible to do that, since I guess this is the first mobile mining project.

I guess most of coins with pos were already named here. As for the question about ethereum, it's actually a very good one, since ethereum must go pos some day, it can't remain pow forever. Ethereum byzantium hardfork is sort of ongoing and claimed to be stable, but I'm not really sure anything has changed. The block reward is 40% decreased and the difficulty bomb will explode in a year or so. Thus, eth is still mineable and will not become pos until 2018.

It's really hard to say and investing in ICOs is always risky. Nevertheless, the most popular ongoing ICO is probably Electroreum. There are only a couple of days left with it. Electroneum's team is experienced and the coin itself is British which perhaps makes the risks lower (I've seen one guy who said it is better not to invest in coins made by people from highly corrupted countries). In general, it's all about the idea of mobile mining via playing a game on a smartphone and at least this coin seems to be completely scam-free.

Electroneum is a British currency, so I guess it has nothing to do with Americans at all. As for the currency itself, a lot of people have been talking about it. I think it's not a scam but probably a legit attempt to make cryptocurrencies closer to people through their phones. It's nice they have an app and that mining is supposed to be possible via the phone but isn't it going to make accumulators exhausted? How are they going to deal with that? Their gaming aspect of earning tokens is actually genious though. Yet I don't think it can even come close to bitcoin anyway. I won't invest in this ICO but I might buy some coins after the release.

That depends on what you call 'short term'. It's been a month since altcoins dropped and they are not even close to recovering now, whereas bitcoin was the coin which could give one profit in a small period of time. What if they won't recover at all? Or if they will keep growing very slowly with some regular drops? I think that now altcoins are rather good long-term, because I believe that btc's dominance in general will slowly decrease anyway.
 Well, I guess altcoins are certainly better than bitcoin gold which is actually ruining btc itself and has no real chances of improving mining (if that's the fork I'm thinking about, 'cause there've been a lot of forks planned for the nearest future).

I think there are no strict connections between prices at all. There were times when bitcoin was growing and altcoins mostly followed it. Good example is May 2017, when btc was rapidly going up as well as ethereum, Nem and some growth of litecoin's price. As for September 2017, ethereum dropped till the middle of that month in USD, as well as litecoin and NEO dropeed superhard. Bitcoin dropped at first but than started recovering very fast and has now reached its maximum whereas most of alts are still suffering from the drop of price in USD.

You are right, bitcoin's dominance on the market has grown and I think it was rather unexpected, for more and more currencies were created and getting their bites of the general market capitalization. It's funny, though. Bitcoin was all about being against the center, whereas now it is itself the center of the market, the thing that influences choices of traders and makes them dump the periphery.
Yes, bitcoin is reliable and sort of stable. Yet it would actually be better for people to use different coins instead of concentration on this specific one, because currently the transaction fees are sometimes really high whereas the needed time is still very long. Moreover, surely there are lots of coin offering things bitcoin will never be able to offer, like smart contracts.

I think it doesn't matter a lot. Newbie can make an awesome investment, whereas an experienced trader can make huge mistakes. Too much depends on luck here.Yeah, I guess trading isn't something working out well, especially lately. I remember this awesome time before last summer when most of coins kept growing and it was really easy to invest and get some profit. After Chinese bans a lot of things changed including huge drops in prices of almost all altcoins. Even though they are green on coinmarketcap mostly, they didn't actually recover yet.

Do you see what I see? +173% on coinmarketcap! At first I thought that it's just that the price went crazy on some odd exchange like Etherdelta but no, the current price is accurate on Poloniex and Bittrex! Is it because of this news: http://fortune.com/2017/10/16/ibm-blockchain-stellar/?
I wonder whether it is possible to know about such price changes in advance somehow and not when it's too late to invest.

Maybe you are right. When the prices are low it's usually great time to buy. Yet it is hard to do that, because you see that you sold some btc for investments in altcoins and lost quite a lot of your initial investment but overall lost not so much if you convert the price into dollars solely because bitcoin's price is growing so hard!
I hope altcoins will recover. I still hold stratis, blackmoon, IOTA (long-term) and litecoin (long-term as well).

Okay, here you go. Waves is a platform for releasing customized tokens instead of creating currencies (although I guess you can create currencies as well). Creating tokens there is probably simpler than registering of facebook and that is very important for its potential success. The currency is made by Russians and its creator doesn't seem very professional to me but that's rather a subjective opinion. What is awesome about Waves' idea is that if a token released on a platform becomes demanding, so does the Platform and its original coin. Thus, waves is likely to grow in price with time but who know what will happen in the future. As for the buy fee - just sell your euro for btc and buy waves on an exchange like bittrex, thus you will avoid such problems. You can send waves bought on bittrex to your wallet afterwards.

I didn't find anological news in Russian, so I guess it's more of a speculation about Putin. What I did find is a member of the National Banking Council of Central Bank of Russia Aksakov saying that there's some official research in Russia on the market of cryptocurrencies and that he doesn't believe that Russia will actually release its own currency but perhaps something like that (and he calls it 'cryptoruble' just because it sounds nice for him) is planned. You can see it in Russian here: http://cryptoconsulting.info/ru/2017/news/crypto-ruble-whether-or-not-it-will-be-and-if-so-what/

As this ICO is now over, I can't get the difference between it and icos we call open. They do have a team and white paper, everything seems public to me. Or is the question about whether it is better to invest in an ICO or in a coin after ICO is over? In this case I would definitely prefer the second option, because at least it guarantees you that you surely will be able to sell your coin just as you bought it on some exchange.
As for Cindicator specifically, it does look really shady and is forbidden in the US as stated on their official website.

So I was at the university and a friend of mine to whom I was telling about cryptocurrencies asked me whether it is like the nimses she uses. I had no idea what Nimses was at that time and everything she was saying was both making me think that it is a cryptocurrency and that it is not. Today I finally googled it and found out that the project is wholly Ukrainian, so most of you guys probably never heard of it as well. Here's their official website: https://nimses.com/.
What I know so far is that it is a social network for smartphones where each minute of one's life generates one nim (virtual coin) and sends it into the wallet which is embedded into one's profile in the network. One can buy coffee, burgers and stuff like that in some cafes paying with these coins! This looks like a mobile phone mining to me, but on the other hand there's no information about nim as a cryptocurrency. Could you help me find out what that is or at least point at similar projects made by Americans or someone else? In Ukrainian wikipedia it is written that nimses is fully unique but this information might not be very trustworthy,

It is still not on Bittrex. And don't forget that a lot of people probably lost huge amounts of money investing in this coin in August. The price is still hugely down even though it's now 43% up on coinmarketcap. It is surely a risky investment and what's more there was already the case where most of coins were down and this one was 50% up. 0x is a nice project and I don't understand why is district 0x even around.

Good point about market capitalization rather than the price, for it's obviously more important. For example, melon is worth $70 but nobody cares, because it's marketcap is just some 49 million dollars and trading volume (another factor to consider before buying an altcoin) is around $220k.
The problem is that some coins drop and don't even recover from the drop and this makes one still lose a lot of money. A good example is dogecoin which is not that bad but is dropping in price with time even more.

IMO stratis has no potential and is a clone of ethereum with pos added to it. At least, I haven't seen anything interesting in their whitepaper which mostly simply explains what blockchain, smart conrtacts and proof of stake is. Yet I am sure that the price of less than 3 dollars is good, because, as they have good marketing and a lot of people believe in this project for some reasons the price is likely to at least reach $6 thus providing a 2x profit which is awesome short-time. I guess I'll sell my NEO and buy stratis right now.

There's been a lot of discussions about spotting a good ico and differentiating between good icos and scams. I think the main things to remember are as follows:
1. Website. It's important for ICO to have a website and it should look impressive.
2. White paper and team. You should read the paper and info about the team to find out whether the ico is potentially legit.
3. Number of participants in ICO. I think that the more people trusted the ICO and invested in it the less risk it is for you.
4. Where there other projects like this? Is the idea truly innovative?
5. Is the goal of this ICO at least potentially achievable?

I get this argument, but isn't looking at currencies only if they have blockchains a big limitation? Why not to see something else, something completely different and yet working? Perhaps IOTA just has bad marketing. Maybe if they made nice videos on tangle technology people would've trusted this currency more.
I don't know what you mean by those rumors, because I took a look at their dev team and saw that they hired a lot of new nice people in September and the team in general is rather experienced and seems totally legit and reliable to me.

Well, you are probably right as for right now but IOTA's been going down even when other coins were doing okay... It's still #10 in marketcap which is nice, but I think that even that is not fair, because it's more interesting than DASH and litecoin IMO.

You tell us, for your investments appeared to be extremely successful. After investing in eth and ltc which turned out great, I tries to make short-term investments but as a result lost about 35% of initial investment already. Seeing how fast btc grows I am trying to think that probably the easiest solution is the best one. Maybe we should stop thinking so hard about proper investments in altcoins and simply keep the money in btc.
