Buterin delivered an accessible overview of cyrptoeconomics, which he defines as the fusion of cryptography and economic incentives to achieve information security goals. Buterin comes off as a brilliant, likable guy, in part because of his ability to distill complex concepts with ease and levity (for example, he refers to zero knowledge proofs as “spooky advanced stuff”). He also doesn’t seem driven by ego or wealth, despite the increasing number of applications that are built on the Ethereum protocol.

Yes to get fixed income from trading, we must traded on different altcoins especially the altcoins that has sign trend up
or choose the altcoins that has high fluctuating of the price, the fluctuating of price are different every the altcoins
 so traded on many altcoins has big chance to getting fixed income from than just traded on one coin.

that is good idea to save the bitcoins before we die and making our bitcoins never lose forever, but the problem on the dead men there are no peoples around the world who know when will be die, there are no acurate sign about the dead will some people, the best time to teach our children is now because we are still alive.

Yes i agree with you, we must invest on the right ICOs projects, before making investment on the ICOs we must learn more about the projects of the ICOs, we need data about the projects ICOs, are the ICOs will used on real business, entertainment or other funtions in the future? Are the ICOs has numbers of comunity that take the beneficial of the projects? The factors of fundamental must be learned carefully.

I don't agree ethereum is good for long time investment because ethereum has high fluctuating of price,
ethereum will be suitable for short time investment (trading bitcoins to ethereum) we can take chance the profit
of fluctuating ethereum's price and the altcoins for long time investment are investing into the ICOs projects because
the chance to getting large of profit on the ICOs projects that has real products.

Since last week’s bitcoin hard fork, we have received a lot of requests from our wallet users to include Bitcoin Cash support.
We are excited to say that the Bitcoin Cash wallet is now live, allowing you to receive, send, and securely store your Bitcoin Cash!
The Bitcoin Cash wallet is currently available as a web wallet. The mobile app version is coming soon!
I have got the information about BTC.com support for bitcoins cash BCH via email, that is good for BTC.com
Congratulation for all of the user's BTC.com wallet.

I will give the bitcoins to my as a wedding gift, if my friends are comunity of bitcoins or they know about the bitcoins
and know how use bitcoins, at least they know how to sell the bitcoins on the markets,
but give bitcoins to the people who don't understand what is bitcoins, it will not be appreciated, it will be considered as
something useless and i don't want burn my bitcoins.

For me problem with ICOs is must making analisys fundamental of the ICOs projects, it needs long time before i make investing into ICOs because many scam ICOs out there, i must search the ICOs projects that has real business, has comunity of the ICOs projects, developer of ICOs that has knowledge about their projects and the ICOs can be applied to real life many people know about this business.

I don't understand what do you mean with switch from bitcoins to bitcoins cash, but if you mean with claim bitcoins cash you can try to bittrex exchanger, you can get free bitcoins cash BCH, of you hold the bitcoins before the bitcoin's hard fork happened of course you must have the private key, but if you mean with switch from bitcoins to bitcoins cash, also you can use the market to exchange BTC with BCH. Because BTC and BCH are different coins with different blockchain.

Almost all of the used doesn't know about this projects, where you got about this information? the projects looks nice to investing but you don't give us more information about it, will be better you give us about the link of website and any other information related with this projects, the comunity of bitcointalk will check it, is it legit projects or not.

Bitcoins hard fork was not wrong, it happened because of be supported by almost all of comunity bitcoins themselves
it is just about the choice the people who agree to bitcoin's hard fork they can be bitcoin's users and support for it
and the people who doesn't agree with bitcoin's hard fork can be support bitcoins cash the best results from the bitcoin's hard fork is the chain of bitcoins and bitcoins cash are alive now, so depend on the comunity what will be choosen.

If you want sell bitcoins to Paypal or you can buy bitcoins with Paypal, you can use https://paybis.com/ service it is can be trusted in my experience and many choice of method payment to buy and sell bitcoins on there, unfortunately paybis apply the fees transaction to trading on there but trading on there is safe.

The problem on poloniex in my experience, when i was login to poloniex it will be logout automaticly couples times tried to login but the same problem came to me and i have heard about the coins on poloniex could not be withdrawal,
The problem on bitfinex the verification on there are very difficult because many documents be needed to get verified
The problem on bittrex is on their website doesn't support be accessed by smartphone devices, so right now i used Kraken to trade popular altcoins.

Yea, ethereum is gaining right now, ethereum's price is trending up it will be around $300/ETH because the trend up is strong we can make analisys technical with cryptowat.ch  https://cryptowat.ch/poloniex/ethbtc/1h we can change the time prime depend on the strategy of trading and the market be used for trading ethereum.

I think for gaming altcoins, i choose Enjin coin, it is the ultimate cryptocurrency for gamers! Deploying on thousands of gaming servers and beyond on the Enjin Network which has over 18 million gamers and 250,000 communities.
Even on Enjin coin, i can make investment in gaming altcoins, here the detail about Enji Announcement Thread: https://bitcointalk.org/index.php?topic=2042871.0

While many investors view Bitcoin as digital gold, ETC can be viewed as digital platinum. In the same way the platinum has store-of-value properties and and general industrial applications in the physical economy, ETC is an asset with store-of-value properties and broad industrial applications in the digital economy. https://briandcolwell.com/2017/07/ethereum-classic-digital-platinum/.html
Interesting an article for comunity of ethereum classic.

Totally agree with you, ICOs projects are part of instrument of investment in digital coins, we must can make analisys fundamental of the ICOs projects are like who is the developer of team? How much amount of comunity of the projects ICOs? What's funtions of ICOs in the real life, it will help us from getting scam and less risk losing money in ICOs investment.

Bitcoins cash BCH doesn't has supporters (developers, comunity and real investors) BCH's price was increased on first day launching is just be pumped by the traders with large of money, they are not really invest in bitcoins cash, just taking short profit of wild fluctuating of BCH's price, so righ now bitcoins cash will be difficult to be pumped again (maybe BCH will be pumped again couples months later, if BCH can survive in digital coins world).
