Each transaction occupies a certain space on the blockchain, the ledger that's distributed across nodes in the Bitcoin network. The more space you occupy, the higher fees you pay. The faster people want to get into that ledger, the higher fees they pay to get into that ledger. thereby, Fees aren't determined. you can select any fee you want and a miner can choose to include any transaction they want. Block space will always be a limited resource with competition for inclusion.

If we check history, when Bitcoin crashed from $1,000 to $200, bitcoin only pumped back to $1000 when their dominance got pumped as well. and then, finally the whales dumped their bitcoin for altcoins for few months. And, during the bull market 2017, once again bitcoin dominance got pumped all the way until November 2017. alt season only lasted in less than 2 months before market crashed. Thereby in my humble opinion, the dominance percentage doesn't really matter here. people dump bitcoin for altcoins when they already gain good enough ROI and vice versa.

Most of the time it isn't even necessary to wait for one confirmation as long as you can verify the TX has been broadcast and the appropriate miners' fee is included. But every confirmation adds security and trust so it really depends on how much you're getting. what you have to ask yourself is, it's worth the time, effort and resources for someone to commit a double spend for this or not.

Starting with Brave browser isn't a good idea. I would start by explaining the blockchain, which is the very essence of cryptocurrency. then moving from the blockchain, I would move to the ever popular, Bitcoin. After they have a solid understanding, I would introduce other popular altcoins, such as Ethereum, litecoin and Ripple, since these are fairly high caps, it would be good to get a solid understanding of these too. then I would follow with an introduction into other altcoins suck as Brave browser and ICO’s in the end.

I prefer decentralization because there are a very good benefits to scaling in a decentralized way. for one there’s less initial cost involved, users around the world are providing the computing power. There is a much lesser chance of the network going offline, natural disasters, electricity outages, etc. happen in the real world but geographically disparate computing mitigates that. Associated with that risk is regulatory cost, which is also mitigated by decentralization. You also have a much more secure system where people can’t just hack you and steal the money in the system like keeps happening on centralized exchanges.

I won't. as I sold off %60 of my holdings in Jun when I decided the stress of watching the price wasn’t worth it and it was about time for me to take some profits. the %40 I have left invested is what I’m comfortable with, after taking that profit, so that’s true “HODL” money, and putting much more back in would make me over invested again. thereby with the current prices, and having done some work to my house with the %60 I withdrew, I’m about ready to start buying in again slowly.

As we can see mining is currently stagnating or even in a slightly growth phase while prices are declining. this means that mining is getting more and more competitive and that miners will be forced to sell an increasing share of their freshly mined coins just to cover their electricity bill. This selling pressure leads to lower prices, which in turn forces miners to sell even more Bitcoins to cover their costs. that's what happened 2016 and that's also what I expect to happen again. However, It won't play out exactly the same way because people are learning, but they are not smart enough to fully take these mechanics into account.

I think, trying to time the market is a bad idea, and will end up eating at your brain. the easy answer is to do dollar cost averaging, buy every pay day a set amount, and do this for a few years. this way you buy when it is high and you buy more when it is low. This is one of the most common and successful investment strategies that reduces your risk and producing long term stability and gains.

however, If you are worried that you missed the Bitcoin Boat, and if you can take a long term view, I can say the right time to buy Bitcoin is whenever the cost is less than US $14,000.

If we want to be entirely fair, Satoshi's dream was that bitcoin basically replaced every single currency out there, and if you believe that fever dream is possible then you can theoretically take the value of everything on the planet then divide it by 21 million Bitcoins. obviously it's sort of an insane Bitcoinist fantasy, but it is at least theoretically possible to have a $10 million per Bitcoin, and practically any valuation in this range would require the US dollar, Euro, Pound, Yuan, Yen, Rupee to go through extreme hyperinflation simultaneously.

Yes, but not as much as before and the act of making a profit on them is getting harder as competition is getting though. there's always going to be opportunities, and they grow in number when volatility is high. sometimes, there have been coins that were selling for a lot more on the Korean exchange than others, for example chainlink, and people that were in Korea could buy on binance or idex and sell on bithumb for a profit. however, arbitrage from local fiat currency, to a foreign currency, to crypto, back to local fiat currency is extremely profitable.

They seem to fall into two broad categories. on-chain and off-chain. on-chain scaling requires the developers to change one of Bitcoin's properties such as block size limit, transaction format, transaction signature format and etc. while off-chain scaling refers to approaches that increase the utility of the network without touching the blockchain. for example batching multiple payments into one transaction, virtual payments within the system of a custodian such as Coinbase, payment channels or lightning network, sidechains and etc. Off-chain is backwards compatible while on chain scaling isn't. On chain code is simpler and easier to maintain.

Cryptocurrency is already changing the world and will continue to do so. it as a tool of commerce is still in it's infancy, but every day seems to bring new innovations that will enable the inevitable change. like many disruptive technologies before it, the change and full acceptance will take time. But it is happening right now. Wall Street and many governments are going to ignore Bitcoin until it is to late for them to act. they are too slow to react the the new winds of change.

You could be sponsored by industry. some companies, for example BTCC, Blockstream and Bitpay, and individuals need to develop certain functionality in the Core, so it makes sense for them to pay select developers to implement those features. Of course, there has to be consensus among all developers and contributors about proposed features before they can be implemented. a company cannot force contentious changes simply because they are willing to pay. Core, not being any kind of an actual organization, but there is info on the website about how to offer to sponsor work on a specific proposal.

I think the Bitcoin environment has enough competition against it to dissuade any monopoly. think about it, Bitcoin gets controlled by one government or company, and starts to under-perform. if this happens, investors leave the market, developers move to a Crypto that doesn't limit their goals, and Bitcoin price tanks. when all the attention leaves Bitcoin, we see those monopoly holders losing massive profits. If those monopoly holders put in a large financial investment, we see them operating at a loss. a monopoly is not necessarily bad. But, if Bitcoin turns into a bad monopoly, the exodus to another crypto will be quick and swift.

I think the majority don't like Altcoins because they don't bring something to the table significant that Bitcoin can't do. altcoins were just invented so people could mine them and try to get rich following in Bitcoin's steps. actually altcoins bring nothing to the table except an experimental testing ground for changes to be merged into Bitcoin. further, we are having trouble as is trying to get 1 digital currency to be understood and accepted by the mainstream. adding the dozens of altcoins into that would make them dismiss bitcoin and all digital currency altogether.

Yes, Of course. Many professional analysts estimate 6-digit valuations per Bitcoin. even McAfee made that legendary wager to eat his *thing* if it doesn't hit $1M each by 2020, albeit it's not real now. Bitcoin is basically the only inflation-proof asset, currency or everything you named. Only 21 million will exist ever, and people are continually losing coins by forgetting passwords, sending to burn addresses, losing hard-drives, dying without passing on their coins and etc. Not even gold is that scarce, we don't know how much gold is still underground to be mined, and asteroid mining could crash the entire gold market.

Bitcoin is has the biggest market cap and volume trade per day so it works as a market thermometer. traders use bitcoin’s as an indicator of market felling and wait for a good move on bitcoin to enter theirs trades on other coins. However, I would say to remember that the relationship between BTC and altcoins is not always symbiotic. there are time where money is flooding into BTC and the altcoins are bleeding because the money is being taken out of altcoins to go into BTC. I just see an influx of money to both sides which is causing everything to be positive atmosphere.

When using mainstream exchanges like Coinbase you can be rest assured your funds are safe. However, they do have some restrictions and KYC sometimes takes ages. Even with a verified account they will hold your funds for 30 days and your value will drop most likely. whoever suggests coinbase isn't experienced. Thus, i think the easiest and safest way is just to use Binance, which takes Visa and Mastercard, and only 10–30 minutes to get your BTC once purchased.

I think the most important thing is, learn to control your emotions. It's human nature to get excited when things go up and get depressed when they go down. If you do this you will buy high and sell low. You need to train yourself to get greedy when everybody else is fearful and fearful when everybody else is greedy. Also, collect as much information as you can. success in trading and any business comes from being contrarian and right; managing your emotions helps you be contrarian, but you still need to be right.

In my opinion this is good to force people to treating exchanges like banks. however, you should not be keeping your coins on the exchange because leaving stakeable coins on an exchange leads to centralization of mining or staking power which is bad and counterproductive to the security principles of blockchain technology. also If the exchange gets hacked or pulls an exit scam, all your coins are gone forever.
