In crypto world the best/top exchanges keep on changing. Earlier it was the bittrex/poloniex era now its Binance and Kucoin era.
Binance and Kucoin are definitely the best exchanges currently. They have a beautiful user interface and are very easy to use exchanges.

Exchanges have made the withdrawal fees a nice way to extort users. Ethereum transaction hardly need more than 40 cents to confirm in few blocks and they charge up to $10 for its withdrawal. If you are going to earn through withdrawal fees than do away with your exchange trading fees.

You are better off hodling your coins than trading them and ending up losing them. Also according to stats you are likely going to make more return if you just hedl your coins then if you were trading with them.

I would recommend LocalBitcoins for buying Bitcoins without any id verification needs. Also you buy through cash so you also avoid any trace of purchasing it. Have been using it for few years now without any issues. Also try to stick to the platform and don't do transactions with someone outside the platform as you get exposed to getting scammed.

Trying to mine on a smart phone is like trying to travel the world by foot. No matter if you buy the latest and most powerful smart phone in the market, you will never be able to earn more than a few cents and that too after months of continuous mining if not years.

Firstly, it is the ease of using Binance. It has a beautiful user interface which is really easy and nice to use.
Secondly, it has huge volume on its exchange. Everyone wants to trade on an exchange that has liquidity as selling on such exchanges doesn't cause huge drops in price and are more trustworthy in the eyes of traders.

He meant in the context of market cap and the no.1 coin title.

@OP - Crypto world is completely different and no one can predict what can happen tomorrow. You should always expect the unexpected.

Just withdraw them from Mercatox in your Nano wallet and only transfer the amount you wish to sell onto Binance, as keeping your coins on exchanges is very risky. Never hodl your coins on exchanges.

Hardware wallet are the best wallets. They are the most secure way to store your coins. Trezor and Ledger are two that I know of that are good. Once you have more than a few hundred dollars into cryptocurrencies you should invest into buying a hardware wallet.

That's the beauty of Bitcoin even if countries ban it they can't stop it from growing. It is a decentralized currency with no single point of source. Even if some countries ban it other countries are accepting it. There is positive news coming out of China, South Korea, Japan, India, USA and many more countries in regards to laws concerning Cryptocurrencies. So I don't see Bitcoin being destroyed any time soon.

I don't think more than 10% of coins will survive past few years. If you look at ICOs from last year than 47% of them failed, which is a high percentage. With that rate only the coins that are continuously innovating are going to survive.

You can checkout the Blockfolio or Delta app for android and ios. You can input your investments into it and it will show you exactly how much you are making or losing from that investment into a coin. You can also add coins for just watching their prices. These are good apps for keeping track of how much your portfolio is in the plus or minus.

The most common one currently is the twitter reply scam, where someone posts a reply to a famous person with send x amount of eth to y address and youi will get 5x amount of eth back. People are actually falling for this scam and everyone needs to be made aware.

In simple terms you can think of it as something that removes the not so important data from your transaction which helps in reducing the size of your transaction, it helps in reducing the fees that you pay for the transaction. The Electrum wallet supports segwit.

Yes exchanges charge fees for transferring coins from their wallet to yours. The fees are generally a bit high for transferring which at many times makes the amount of transfer equal to the fees. You are definitely going to feel a pinch if you are going to transfer your coins frequently from exchanges to your wallet.

There are faucets and other websites that give away free coins but the amount is so low that it would be better spending your time in actually earning some money in real life and then buying the coins.

The most important point in this post is holding your coins in your own wallet and not in some exchange wallet. As time has shown again and again no matter how good an exchange is there is a high chance that it could get hacked.

Bitcoin transactions are irreversible so there isn't much you can do after you have sent the payment. But you can use an escrow service to prevent yourself from fraud or only buy from trust worthy web stores.

In cryptocurrencies you are more likely to earn more if you just hodl a coin than trading. If you aren't experienced in trading then you shouldn't dive into it. You need to research into this field for at least few months then think about anything.

You shouldn’t be afraid of hackers much if you are holding the coins in your wallet. I have been holding my coins in my wallet for few years now and never been hacked. You just need to take some precautions and some common sense when visiting websites. Although if you hold your coins on an exchange then you should be very afraid as exchanges are more likely to get hacked as they are always in the eyes of hackers.
