Bitcoin hit a record high of $19,783.21 in December before plunging, but still rallied by over 1,300 percent in 2017.
The fall in bitcoin's supremacy is due to the rise of other cryptocurrencies such as ethereum and ripple. still being first ever digital currency BTC dominates 45% market capital today. 

yes it is. in fact i suggest you to try waves yourself. its really awesome that you can create your own token and sell them on market. Waves accepts the payment in three different fiat currencies and BTC & ETH. you can create your favorite token for one WAVES ( Waves native token).

Bitcoin's younger brother litecoin. it was the first official altcoin and has great potential to raise in future. it even make the transaction much cost effective and faster compared to bitcoin. moreover, it is currently trading at 5th place on market and it must make great alt coin for trading.

Because Ethereum blockchain is ideal blockchain for mass adoption and easy to deal with. Even Microsoft has started building their Azure platform on Ethereum blockchain and IBM is working on it as well. Ethereum blockchain hold way too much potential to turn around things in way better and faster. 

Waves is really interesting project but still in its development stage. though it raised $16 million during ICO. Ethereum is keep growing and i suggest you to hold them as there are number of project lining up based on ethereum blockchain. as investors point of view holding ether is better.

Always paper or alternate way of cold storage. i cant really trust with hot storage devices for certain reason. i will just print my keys, laminate them and place them fire secured place. or i would do something similar like craving the key on metal or something like this. paper wallets are easy to deal with. on another hand hot storage like Ledger Nano S can be very expensive and vulnerable at the same time. i can print multiple keys with paper and place it all the secure place for back up. i cant do that with hardware wallets. though paper wallets serves best back up option. 

The trend has already been started. new consensus mechanism such as proof of stake and hybrid of POW and POS is already created that will not require much energy in order to mine Bitcoins. moreover, the energy efficient hardware especially made for mining has already started production and one of the prime example is ASIC hardware. may not now but in future, if not bitcoin other currency sure will be easy to mine.

I will totally support waves. Waves is different from Bitcoin for better. and i love Waves for few more reasons. first it allows you to create your own crypto tokens, second it accepts USD, Euro and Chinese Yuan as payments, third, it is faster, secure and transparent and ready for mass adoption. For me Waves is much better then Bitcoin.

I suggest you to buy some bitcoin instead of mining some. mining hardware can cost you hefty added with power consumption. even if you buy special ASIC hardware for Bitcoin mining it will not turn quite profitable at smaller scale. you will need larger farms to mine bitcoins with top tier mining hardware and other set ups. of course, it is gonna cost you enormously. well go ahead and create your own mining farm if you have millions. buying fraction of the coin will be most appropriate as per current BTC price.

No bitcoin isn't stable at all. in fact, we have seen enormous fluctuation in bitcoin price in last year and it made it literally volatile. let's have look in past to get idea regarding bitcoin price fluctuation.
Bitcoin hit an all-time high (albeit briefly) of US$1,124.76 on November 29, 2013 and In mid-November 2015, it reached $2200. it was the time bitcoin was rising steadily. The steady rise of the Bitcoin price finally resulting in something called bitcoin big bang on 15 December 2017, when it topping out a whopping $17,900. Unbelievable right? Though bitcoin could not hold that astounding price losing one-third of its value in 24 hours, dropping below $14,000 on 22 December 2017. On 5 February 2018, Bitcoin's price drops 50 percent in 16 days, falling below $7,000. Though it managed to go up again and currently trading at $9110.01. These crazy deflections in Bitcoin’s price clearly indicate  that it is not stable.  

I tried with brainwalletx and Electrum but both failed to verify. Try signing new signature without new line. Line break sometimes causes troubles. And verify it yourself with https://brainwalletx.github.io/#verify if it works, it should work for me as well.

$25 is a small price actually. I remember when I searched for physical card before they were banned by VISA, they costed much more, especially if you wanted large limit like $10,000 or something. Okay, they could decrease price for virtual card, that is true.

The reason for ban on crypto ads is not that Twitter is against cryptocurrencies or blockchain. The reason is large number of scam ICOs and crypto "services" like HYIP programs. And they thought that they need to protect users against these scams. But in general, they are in favor of the technology.

Because of the semi-anonymous nature of Bitcoin, it’s used in ransomware attacks. Hackers breach networks and hold them hostage until payment is made to them. Hospitals and schools have been victims of these types of attacks. However, unlike cash, which was favored by thieves in the past, Bitcoin always leaves a trail in the blockchain that investigators can follow.

Bitcoin is a new and interesting evolution in how people trade value. It isn’t backed by any single government or organization, and it’s only worth something because people are willing to trade it for goods and services. People’s willingness and ability to utilize Bitcoin fluctuates a lot. It’s an unstable investment that should be approached cautiously.

Bitcoin has a limit to the number of tokens it will release. That number is hard-coded at 21 million. The estimated date of Bitcoin issuing its last coin is believed to be in the year 2140. No one can predict what will happen at that point, but miners will always earn some profit from transaction fees. Plus, users of the blockchain and the Bitcoins themselves will be incentivized to protect the network, because if mining stops, Bitcoins become vulnerable and so does the data that has been locked into the blockchain.

Bitcoin is the opposite of a pyramid scheme from the point of view of Bitcoin miners. The Bitcoin protocol is designed like a cannibalistic arms race. Every additional miner prompts the protocol to increase the difficulty of mining. From a social point of view, Bitcoin is a pure market. The price of Bitcoins fluctuates based on market supply, demand, and perceived value.

As far as i know Bitcoin is really secure. Thanks to its proof of work and proof of stake consensus mechanism. these consensus secure the bitcoin blockchain from issues like double spending and attacks like 51%. As long as you are not sharing your private keys with anyone Bitcoin is really secure.
