I think you should have saved crypto asset in wallet where you will have access of private Key. keep all crypto in trading platform will not be secure way to store. BTW every person has different set of mind but I would prefer wallet rather than any exchange.
There was many cases in last year where exchanges account got hacked and stolen crypto asset.

Actaully facebook is seen so too much trouble after data leakage, That's why they want to get away from controversial things.
What we have seen on facebook is ICO ads and most of ICOs are Scam now a days, That's why facebook wants to take distance from them.

Yes We have to use recommended wallet security features such as Email verification or Google Authentication. It will give more security to our wallet from phishing attacks. Let me give me simple example of mine On bitfinex I don't put any security feature ( 2FA ), Two days i got email that someone just login your bitfinex account that means hacking of wallet without google 2FA is easy for hackers so that's why it is recommended for you.
 

The man who is professional trader is also a good analyst because without analysis you can't be professional trader.
You need to examine and determine the best opportunity to make high profit, it will only achieved if you predict accurate or precise value for investment.
There are many books available that can help you to know better understanding to techniques and terminology.

I don't know about Storing file on blockchain but i wanna add one thing in this as we know blockchain is super secure why not some one invented a drive or memory space which is encrypted by blockchain and works like same as wallet works on private key. It can be more secure feature to store your files because no can access yours files without private key.

anyone who can claim that he/she can predict price movement of crypto for next week. Prediction only valid when there is no future constraints and we would have stable historical data , than we can easily says what is going to happen in future but in crypto world we don't know about govt.behaviour toward crypto, you can predict price on the basis of history but it is not valid because of govt. and other factors.
I would suggest you to Hold it.

I have seen in crypto world people has different psychology some has patience and some don't have.  What i observed is people want to take risk but don't have patience, when price drop they sell their crypto in panic selling.
Getting rich in very fast pace from crypto is also psychology of most of people, but it is not that easy we think, from getting profit from crypto you have to good analyst and researcher.

First of all i want to talk about GOLD why Gold?
A decade ago Gold was the best asset to trade, Still people use to trading in gold because it is very less risk involved. If you compare historical price of gold than you will able to find that gold seems very stable. That's why people hold it.
now Why Bitcoin ?
Bitcoin for those who want to take risk and hold it for more than 1 year, People find bitcoin more secure because of its digital form. No threat of theft if you used Hardware wallet or any trustworthy wallet. People take risk because bitcoin can give profit in very less time as we have seen its prices. Last year it was around 2000 USD in may 2017, and in December 2017 it was around 15000 USD, so this is the real reason why people hold bitcoin.

KYC is mandatory in crypto because at least companies can be able to know whose their investors, bounty etc. It is also important because there are some countries which are not allowed their citizens to invest in ICOs so companies can easily identify those people.
Even when we are investing in stock market let's suppose if you want to invest in IPO than you need to be register on portal and going through KYC procedure.

It is the time for new investors in come in the crypto currency market because as you know right now market is on red line and maybe next month it may grow. According to me it is best time to enter into crypto world. I know some people which were invested in crypto in last year December, now they are crying. but you guyz have an opportunity to minimize risk to get huge profit from it.

Risk taking does not mean that you will invest in any coin without doing any research and analysis if you do so it will lead to huge loss for you.
It is always suggested if you wanna to invest in crypto than always invest in popular coins like bitcoin, ETH, LTC, BCH or many others.
because there will be higher probability that their price will gonna rise in near future. This investment can give huge profit out of your investment.
Now a days right time to buy these coins because they are in very low price as compared to few months ago.

Guyz I want to add one thing, Blockchain can be used in Voting system because as we all know once hash create, we can't change it. we can only see these hashes whenever we want.
Like in cryptocurrency transaction we have transparency we can see transactions detail of each and every address, how much he/she sent or receive. but we can't change information from these  TX ID.
There are many areas in which blockchain can help.

I personally used WazirX and i have not faced any major issue with wazirX. It is very new in P2P but result quiet very impressive because most of indians have used their platform for trading. also dispute management system of wazirx is also good, there is no chance of getting fraud by someone.

According to my point of view banks will never offer bitcoin deposit because bitcoin decentralized in nature. And one thing more Banks find crypto as a major competitor. Let us suppose if banks start depositing and how banks earn income because banks earn income from interest paid by loan holders.

Actually if there is ICO than we must have to concern with its product or service where the tokens can be used.
if there is no use of tokens than what is the fun of investing in particular ICO.

Both the markets can give huge profit but there are many differences in between them first of all centralised and decentralised is one of them.Investment in-stock market may be much more secure but it will not give such big return as crypto currency can give . But cryptocurrency is not much secure and stable as stock market.
as we all know every thing has two sides. Investment is all depend on person whether he/she want to take risk or not. wanna huge return at highest risk or normal profit at optimum risk.

Bitcointalk is a platform for promotion of ICOs, I don't think that without bitcointalk any ico can successfull. we have seen there thousands of people which are crypto enthusiastic and willing to invest in crypto ICOs. we may use some other platforms like moonforum, etc etc. but they are not effective as bitcointalk is.

Creating a cryptocurrency is not a difficult task but make circulation of particular is very difficult. for this you need one product or service which will be connected with that crypto currency. This will make people to buy your crypto.
so before starting any cryptocurrency, you must work on application on particular in terms of product or service.

Right now bitcoin business is really risky because of regulation but there are so many example set by people.
but business is totally dependent on market and regulations.
countries like Japan, bitcoin business can be successful.

Project without product or service is not possible. If you see any big company beside crypto world can you tell me any company name without product or services. company won't survive without it.
Let's take an example of amazon -- Shopping service, Alexa product, Go, prime they are doing continue Innovations.
In crypto world there are many project which are actually working on their product or services.
