In my experience invested in mining altcoins was not profitable because the difficulty of the coins was increased and the price of altcoins decreased, it made me difficult to get return of investment, buy the altcoins and hold for long time or trading altcoins is more profitable than mining because i don't have to pay the cost of mining activities (pay bill electric, internet and upgrade hardware miners).

Ouroboros:  proof-of-stake-based blockchain protocol.

Ouroboros

The unique characteristic of Ouroboros is that the protocol was developed in tandem with a proof of security that aims to communicate in a succinct way that the proposed blockchain protocol satisfies the properties of a robust transaction ledger. Central to the proof is a combinatorial analysis of a class of strings that admit a certain discrete structure that maps to a blockchain fork.

I just traded bitcoins fair altcoins and some amount of profit be invested in local stocks markets,
choose the bluechip stocks for long time and we will get the dividen of profit from the company,
 for short term investing trading of course trading in digital coins (altcoins) is more profitable than stocks
but for the saving of whealty stocks are best choice and we will get passive income too.

I don't think if we use huge capital to play gambling will be profitable in long time because play gambling depend on the lucky of gamblers but with large of capital will be more good to makes gambling games website, it has chance to getting profit from fees transaction on gambling games than just play gambling with large of capital.

No you will not get the unit value in bitcoins cash BCH not BCC on poloniex, because poloniex market doesn't support this feature
 but if you have bitcoins before 1st August 2017 and you keep the private key you will get the unit value in bitcoins cash BCH
 You can claim bitcoins cash that support for it, but you can not do it on poloniex, you can claim on bittrex to get your bitcoins cash.

Well you can not stop growing of token ICOs, it is new model business in digital coins and new instrument of investment
you just needs stay away from the untrusted projects and choose the best altcoins
 depend on your results of searching about the altcoins and ICOs projects will be choosen never use large of money to investing on altcoins, it will makes you nervous, just use a little money.

No even bitcoins solve its problem, die or life digital coins depend on the comunity of the altcoins
include litecoin, many people said like this litecoin will be die and something like this,
the fact litecoin is still alive until today, litecoin's price was increased and the updating on litecoin's network
with the segwit on there, it will makes litecoin more be strong.

Yes but you should carefully investigate the “sale agreement”, the main legal document between the investor and the company, launching ICO. Then ask about business reputation of people who stand behind ICO data, whether they have been working for a long time in the relevant sphere of activity, does their reputation carry any dark spots, for example, organisations of projects that constantly get users’ poor reviews. Besides, the existence of registration, escrow-account, technical correctness of “white paper” provided by the company which launches ICO are also important. The existence of ready-made well-functioning prototype (a program or a device) also creates a good impression

The most profitable altcoins to be mined with cpu depend on the price of altcoins and the difficulty of mining
the price of altcoins always fluctuating and the difficulty of coins always increased,
basically will be hard to find the most profitable altcoins to be mined by cpu but there are website that give estimation
the altcoins to be mined can be checker on https://whattomine.com/ to choose the altcoins.

Yes because of 70 Millions coins were ethereum's ICO doesn't mean ethereum is scam coin, because the main of function of ethereum right now is for build dapps and ICOs products on ethereum's blockchain ethereum not to be used as currency or digital asset, ethereum offer smart contract platform on ethereum's blockchain.

I have opened the link of yunbi market, but it was slow respond be accessed by smartphone devices especially android
do you have plan to targeting user's smartphone devices to be your costumers?
If yes, please fix this problem because the user's mobile devices will get the problem to access your service
and they will not use your market to trade digital coins on there. Thanks

Yes invest in the ICOs has potential to grow up numbers of investment, but it has potential to lost the money in the ICOs too, 
I am sure there are perfect ICO because in all of the ICOs projects always there are a little weakness must be fixed by developers and comunity in the future even bitcoins its self still has block size problem, we must choose the ICOs just has a little weakness on the projects.

I think yes litecoin's price will rise after the lightning network is activated on litecoin's blockchain because
it is one of bugs fixing on litecoin's network and it is good for the network also will affect on the litecoin's price,
the other reasons will makes litecoin's price increase is halping block of litecoin. We can see the last halping block of litecoin
has made litecoin's price increase, it will happen in the next halping block of litecoin too.

That is good idea to get bitcoins we can sell our skills to be paid with bitcoins, it is good step to get enough money
to be used for capital trading, actually there are other way to start trading with very small amount of money,
we can try investing into ICOs, it can use small amount of money and the chance to getting profit is big
although investing into the ICOs is high risk losing money too.

Ethereum is advertised to use GHOST protocolfor best chain selection. The calculation is done using "total difficulty". The client will always select the chain with larger total difficulty. However, while uncles are included in blocks and miners are rewarded to include them, they do not participate in the calculation of total difficulty thus do not participate in the best chain selection. This deflicts the goal of GHOST protocol, which should always select the chain in which, including stale blocks, is the heaviest. https://github.com/ethereumproject/ECIPs/pull/71

All of traders switch from investing in altcoins to be on bitcoins because bitcoin's price is up trending
so the traders choose the digital coins that has up trend than invest in the altcoins,
this strategy is good for taking profit long term investment with hold bitcoins than altcoins
basic knowledge of trading always follow the trend of price and never fight the trend.
