I also can not find white paper to read about.

Полностью поддерживаю данного человека.
Но добавлю пару нюансов между выбором для Golang и python
В кратце о своих способностях. Написал полную реализацию с апи Топ 15 бирж где есть пара eth/btc также на основе этих же бирж.
Первое это ихнее документация , я бы сказал так без бутылки не розберешся.
Golang для таких целей не сильно подходит из-за проблем с динамическими данными( В принцие любой язык с жесткой типизацией не подойдет) по причине что очень разнотипные ответы дают биржи и не структурированные данные. Что очень приносит много и не приятного гемороя.
Python в свое время подходит идеально для решения этих задач. Он динамически типизированный что дает чуть-ли не полностью развязанные руки.
А про С++ можете даже забыть , он не для того придуман , также тот же С# он только для винды если вы надумаете с десктопа переехать на веб вариант то вы себе так сказать переломаете все ноги и руки пока это сделаете. Есть питон который работает везде и с всем. Для дектоп винды есть такие модули как tkinter(Модуль для оконых програм работает на многих ОС)  и EXE(для винды чтоб как все) сборка cx_Freeze.

cool, now i know i will never use this

Don't believe a word though. Make your own research in the topics because people in the forum are full of shit and many will lie to you to make you buy or sell or are just misinformed themselves.

"recursive call attack"
"weakness in underlying language "solidity""

google (better than listening to bagholder-talk)

also check out "call for dao moratorium" to see how they did ignore expert opinion because of greed.
The exact attack was pointed out to them and they did ... nothing .. well, they said it was fixed but that wasn't true. Now it blew up in their face exactly like experts predicted. It's a joke for the investors.

Some say it's because of 'touring complete' and it will be very hard (if not impossible) to code secure contracts on that platform. Yes, buggy contracts can even after numerous fixes and upcoming hardforks still be expected. No, the contracts aren't secure for all i know. And also not soon. It's by no means a 'realiable coin'.

Academics said: "there is so many attack vectors they cancel each other out."

I don't think it'll be any good anytime soon. Wait 5 years and look at contracts like this again. Currently it turned out to be useless. Decades of dvelopement ahead. Overvaluing like this was pure madness and rampant speculation with no brains involved.

Do you really build an universal platform that could be used by others, or is it just my dreams and misunderstanding of your plans?

i think Bitcoin is legal on Angola and you could buy it because plenty exchange you could use to buy bitcoin http://www.bitcoin-net.com/How-to-buy-Bitcoin-in-Angola.php#.V3FpbDWVMp0

Naturally, for on-line courses will need to create a special application that will use CRON to pay for training services. This application will be keep track of time and the amount of lessons, etc.
Payment could be provided by students themselves or the organization that runs courses. In this case, CRYPTonFly advantage is that the payment will go from one participant of System to another directly, bypassing the learning Service itself (P2P).

"Instead of transacting via local currency accounts at correspondent banks around the world, the banks convert funds to Ripple's own digital currency, known as XRP, then complete an exchange almost instantly."

You right, CRON is money concept too.
CRON is even more wide category for understanding CRON essence than a money concept.

CRYPTonFly (CRON), as abbreviation of the words "Creation Cryptocurrency on the Fly", is a new global cryptocurrency concept, which appeared at the junction of the Internet, telecommunication technologies and certain activities and actions of human.

CRYPTonFly allows you to create two kind of universal cryptocurrencies, which are parts of a new single digital currency, namely: cryptocurrency/time, based on a time during which the activities/actions were performed and cryptocurrency/quantity, based on the amount/quantity of performed activities/actions. Both cryptocurrency/time and cryptocurrency/quantity empowers your ability to generate money "on the fly" by converting your certain activities and actions into the new digital currency.

r0ach is just trying to sell you Monero proof-of-work bagholding that he bought. His logic is incorrect. See my detailed rebuttal immediately above yours.

The problem is you don't see the obvious categorization here, private money vs public money.  The Federal Reserve currently lends debt based money into existence and charges you interest to use it.  This is obviously private money and detrimental to anyone that's suckered into using it when it's clearly neo-feudalism through usury.  Gold?  Anyone can find it if they try hard enough.  There's no strings attached to it.  It's not debt based.  It's not issued by a central authority.  It's not possible to be extorted by interest or devaluation by some unknown party just by picking it up.  It's permissionless, public money.

The same dynamic exists in cryptocurrency.  IPO scamcoins are essentially directly replicating the Federal Reserve banks, in that they're attempting to charge you to utilize their private money system.  Even if you remove the interest or devaluation aspects, it's still a system of extortion.  Pay me to use my money.  Private money.  It is capitalism, but it's also subjecting yourself to be someone's slave where they make the rules and you're there to benefit them at your own expense.

In traditional Bitcion PoW, the block reward does not benefit the issuer, so there is no master and slave dynamic.  It's public money, just like gold.  Everything else that deviates from this model where the issuer benefits is just a flat out extortion scheme.  I'm sorry all of you people want to get paid, but it's not possible in this domain unless you willingly become an extortionist scammer.  The reason this forum exists is for the facilitation of public money to defeat those private money scams.

The best way for you is to issue your additional coin, which will be backed by your services/goods/time.

You can easily start an exchange, and people will trade your coin to CRON/BTC/USD/EUR. For example, if you are a teacher and your lessons are good, your coin price will grow.

Other people will issue their coins and people will exchange one coin to other.

But there is no way to make one "universal" backed by time coin! Each person/company have to issue their own coin.

CRYPTonFly Business Model may be briefly described as follows:
Advertisers (owners of shops, cafes, supermarkets and other retail and catering networks, etc.) can themselves appoint premium rewards in CRON to users for defined activities and set the size of premium rewards for visiting and purchases in shops, cafes, supermarkets and other retail and catering networks, etc), by buying CRON on any cryptocurrency exchanges.
CRYPTonFly plans to take a small commission from premium rewards.

It's a currency like ETH ....on ETH
