I have never done that and won't be doing it in my entire life either. It is said that we should not be investing any borrowed money into crypto currencies and I find it to be really effective advise as borrowed money if lost becomes a burden on head of one person. It is better to wait until you collect a substantial amount of money to invest rather than to borrow it from another person. Cyrpto currencies are considered a risky investment and that's why many people even if they have their own money think twice before investing any money in it.

As mentioned in the list above the Ledger Nano S and the Trezor are the best ever wallets out there as they are hardware wallets.
Hardware wallets provide the best security for crypto currencies. You will also hear Electrum wallet from many people as the most convenient wallet to use. It is true as it is compatible with all the devices. Apart from all of these wallets, Mycelium wallet has been my most used wallet as it is convenient and efficient to use. It provides features such as custom fees, reboradcast transaction, cancel transaction etc... which not many of the wallets provide. It's seed can be backed up and used whenever we want.

There are many exchanges out there like Bittrex, yobit, poloniex, bitstamp, binance, bitfinex, hitbtc etc... which are the trading platforms for many traders. You just have to open an account with them which is free of cost and then deposit your coins there. You can buy any altcoin  with BTC. Many of these websites/exchanges have multiple pairs to trade coins so that we can buy other coins with those pairs.
Note that there are no fees for deposit but they charge some fees for withdrawals.

I think you must be talking about freebitco.in as it is the most legit faucet site that gives free coins, has rolling dice and the ability to multiply BTC with its hi-lo game. Yes this site is legit and has been running successfully over the past many years. This site has been mine and many others' first way to earn BTC.
One thing I would like to mention in don't stick around with such sites for too long as many end up with all their coins lost. Too much of playing will make you a loser at the end. Faucets are just a pass time and cannot be treated as a source of income.

You should be asking this question in Bitcoin discussion and not in the development board.

There is no way you can stop the transaction from being processed. Fortunately both the addresses are linked to your account and you must be happy for that. The option you mentioned about importing the private keys is possible but not in your case since we are talking about exchanges here. We don't own any private keys when we store our coins on exchanges. So importing the private keys is not possible since you dont hold any private key. Try contacting the exchange itseld and tell them to stop ghe transfer but I really don't think that would help either since they would have already made the transactions by now. Just wait until the transaction is complete and send them back to wherever you want to.

I don't think this would solve the problem as there have already been some hardforks which were been done for the same purposes. The  bitcoin cash and segwit both wanted to clear the issues with bitcoin but yet BTC is still working as it is. All the forked coins has turned into altcoins with BTC running the same way as it was but with more difficulties. So if at all BTC is forked again the forked coin will still be called another altcoin. There has to be a solution to solve with BTC itself and forking wont do that job. Lets see how good the LN helps BTC.

Can you please post the transaction ID as that will indicate what went wrong with the BTC transfer.
Your account obviously wont have any  bitcoins in it since the final balance is zero. The total sent and total received although shouldn't be zero in this case. Either your friend has sent the btc to a wrong address or the coins have moved to some other wallet. Check the transaction and find out the route where the coins have been stored.

I had been with the exchange until the last month and has been using it smoothly for quite a few months. I didn't face any issues with the exchange and I had been using it for staking since all its wallets are online 24x7. So it staked coins just for keeping it in the wallet. I stopped using the site once I sold all my coins which was until the last month. The site may be lagging from then onwards. Their support is good and responses quickly. Try contacting them for any assistance.

Almost all the coins in top list of coinmarketcap are pumped these days. It is not advisory to invest in pre pumped coins since they are more prone to depreciate in price. At the current market rate Eidoo coin is the best to invest in since it has more than doubled in price in the past few days. The coin has great potential and it's ICO was a bang on. The ICO was successful in its goals and raised more than they needed. The platform is launched and has developed over the days. The eidoo coin will surely rise more in the future.

Well if you are making 40k then that's really a good profit according to me. You must continue with the same strategy but should wait a little longer before you sell the coins. Its quite obvious that you are selling way too earlier than you should in order to make a great profit. I was worse than you during the beginning days of my trading as most of my trades went in a loss. Most of the times the market played opposite to my trades. So it is always better to hold a little longer and not sell in a loss.

At the present moment it is not wise to buy Ripple as the coin is pumped too much. It has raised to $3.5 in the past 1 month which is a huge pump in it's price. We should be waiting for a while now to make any investments in it. I don't think investing in it for long term will be a good deal since XRP is an inflationary coin and that makes it depreciable in long term. Trading it will be  a very good deal since it is pumping huge these days. So my recommendation would be to trade it or to hold it for short term.

It's necessary that all the coins in top 100 coins from coinsmarket are the best coins out there. Even if the coins are presently at a low price it doesn't mean that it will necessarily go up. The trend sets the coin's price. If the trend is going upwards then the price might go upwards as well. The top 10 coins could be the best coins to trade but the top 100 coins includes many coins which are not that worthy at the moment. For example IOTA is in top list but doesn't give good profits quickly since it rises only at a particular time when it has some kind of positive news or development in the market.

Bitcoin is still in it's development stage and yet the price has increased so much due to it's growing popularity. The limited number of transactions per second is a bane that Bitcoin has and is a problem that needs to be fixed soon. In my opinion the lightning network will give many advantages to the bitcoin network in terms of speed and fees. Although the on chain transactions will yet have high fees the lightning network will be used for micro transactions. Other alternatives such as segwit and bitcoin cash  might be used at times when BTC fails to facilitate the transactions.

HitBTC traders have been facing a lot of issues lately. The site is giving troubles like stopping the withdrawals, messing with user's trades, increasing the fees without any notices etc... These issues indicates that it is not at all safe now to trade on HitBTC as it might scam the users anytime. It is better to stay away from HitBTC and use better alternatives like bittrex, bitstamp etc... I recommend bittrex as it is most safer than others.

I have heard the same thing from many bitcointalk users that signature campaigns are not releasing these days. The thing is that there has to be a valuable project that is going to be launched in order for them to start a campaign. I guess people are not developing new projects since the investors and developers are already acquired with so many projects. There are many projects under development and it will at least take them quite a while to be well established. It will take a few days or months until the new projects and campaigns are launched. We should probably just wait until they are launched.

You should first try to sell it to a local seller from localbitcoins and then try to benefit from the trade by making the deal face to face. You always have the option to cancel the deal when you are dealing in real world. Get the  cash before you send him the btc. If you don't find the deal to be in your favor then you always have the option to sell it to an ATM. Find out which one gives you more profit and then make the trade.

Every transaction has a fee which has to be paid to the miner for processing the transactions. It is the user who decides what the transaction fee should be. The miner decides which transaction should be processed first. So they generally process a transaction with higher fees first and the people then wants their transaction to be completed first and so they pay higher fees than others. This is how the transaction fee increases day by day and the transactions pile up one upon the other.

Nobody can precisely predict whether the value of bitcoin  could go to zero or millions or not since it is a new currency and globally popular. The currency is yet in development stage and this makes it really difficult to predict its worth. The possibilities are on both the sides and I strongly believe that bitcoin has  more potential to succeed and be worth of millions. The possiblity for it to depreciate in price might come true if the currency does not solve the current problems such as huge fees and confirmation delay but I believe that the lightning network will solve these issues.

The lightning network itself is designed in such a way that it solves the users' needs to make small amounts of payments. The user sends the amount through channels created by the receiver. You don't have to pay a lot in fees as it is now since the the amount you send to the receiver is inclusive of the fees. Once the receiver requests a payment you can decide whether to use that channel or not.

I don't think the fall of bitcoin has anything connected to the rise of Altcoins, as both are different to each other and here in the crypto market each and every coin plays a major role in their self-development area and every single coin is different from each other and it all depends on their one's technology and their services. 2018 is really good for both bitcoin and altcoins and I expect the bitcoin to rise soon as it is rising from the correction which came last month. Even altcoins lie Monero, Ripple, IOTA, Waves are doing a good job and I am personally expecting that all these coins are going to give you more than double returns in this year as they are showing great potential and some good technical patterns in their charts.
