Day trading can be profitable but only if you're better than the average trader and good at managing risk. It's stressful though and hard to predict which direction the market is going short term, i wouldn't recommend it.

In my opinion it is better to trade the more longer term swings in the market which are easier to predict and don't cause as much stress. It requires a lot more patience though, sometimes you have to wait many months for your trade to work out. Easiest and probably most profitable for most people long term is to just accumulate Bitcoin now as long as there is an 50 percent discount from its high and wait for the next bull cycle to begin. This requires the most patience though, but is also the least stressful if you didn't invest too much.

HODL is the best strategy but that doesn’t mean you should never take profit.

I would suggest a strategy based on the market cycle between BTC and Alcoins. If your willing to put in the work it’s fairly easy to increase your BTC position by speculating on Altcoins. Learn the market cycle and try not to over trade or be greedy. Only risk 10 percent of your BTC at a time and aim for 3-5 percent gains, and use stop losses. then try to sell the top. it's not easy at all, but i would advise you to look at the monthly RSI on btc/usd, so far it called the top and bottom of the last market cycle.

Most people lose money because the way the markets move always makes your emotions try to get you to make the wrong move. this is why the patient win. In other words, your highest chance of success is just to HODL or sell at targets. Hence save and HODL most of your disposable income, and play with a small amount.

It is not bullshit. imagine that you had a technique to perfectly predict price movements, then you would always buy low and sell high. By doing that you would alter the market ever so slightly. now imagine that everyone knew your technical analysis, then everyone would buy at the low and sell at the high, but now it’s a competition. You’ll have to sell just before the high so you can sell before the crowd jumps in. But everyone is going to do that. Same for the lows. thereby invalidating the technical analysis.

There are only two ways to make money off of technical analysis. First, finding an indicator that nobody knows yet. But it is an arms race so you will only have that indicator for yourself for a short time before it gets invalidated. Second, create a following and get them to move as one in a way you can exploit.

It may take time to get there, but I have a feeling that next bull will be a memorable one. So many smart people working on infrastructure, solutions, improvements. Next time the bull shows the value proposition of Bitcoin will be so clear, so apparent, that every average person will understand, and this time, unlike 2017, we will have a lot of people boarding but not leaving.

Each prior supply halving in bitcoins history has been followed by a massive bull run. the halving is what triggers it, then price begins to rise and eventually explodes because of FOMO. It then settles at a price that warrants the new rate of supply. The last halving was in mid 2016 which was followed by a small rally up to $1,000 then a FOMO fulled bull run. this is just the natural process of the free market adjusting to the new rate of reduced supply.

There was hundreds of thousands of people worldwide buying BTC to trade for ETH to trade for that shiny new token. There was also countless ICO's popping up on the daily and people rushing to be the first to buy and flip. Millionaires were being minted on the daily until the companies behind some of the ICO's began dumping their ETH for that cold hard cash. Now people see a tiny upswing in price and are running to be the first to call bull run! hurry up and buy. However without a reason for hundreds of thousands of people to trade Crypto like those fateful days of spring 2017, We will not see EVEN the numbers that we had. Especially while people are squirreling coins to cash out as soon as they can.

End of 2019 will be boring. This is based on my assumption that ETH will continue to experience the pattern that BTC developed from 2013/2015. In 2015 BTC basically bounced from $250-$450. I'd guess we will bounce between $70 and $160 in 2019. 2020 it starts to get interesting again. I predict $600-$1000 by the end of 2020 but the real run will happen in 2022 when it could run up to $15,000-$20,000 just like bitcoin did.

Just a small 10% - 20% increase in demand will drive the price one to two orders of magnitude in price. I really don't think people grasp the idea of what a decentralized trustless supercomputer is capable of doing, the last bull run in 2017 was just from people starting to understand what BTC is and what it does. It's going to be a while until people understand what ETH is for. By then ETH will probably be substantially higher due to corporate interest.

When the buyers come in flocks, the price will increase quickly. The whole market is still bearish. right now the people buying Monero and Cryptos in general, are traders. Not many people will be buying in positions because there isn't any clear signs of quick growth. Traders will ride the price down, buying and selling positions as they go, but that doesn't represent the true value of the coin. Just the current buy price. Without checking my facts, the amount of Monero that could be purchased at $300-$400 isn't really that much when you consider the fact that sellers will quickly adjust their price when the bull market hits. In my opinion, Everything is possible.

There are some serious problems that need solutions and we should overcome some hurdles like:

1) Pools and large operations centralize the mining power in the hands of a few. This is troubling and someone needs to solve this by providing proper incentives for being a solo miner and not joining pools
2) Price stability for 5+ years in a row
3) Hyperinflation of major currency
4) Small country adopts Bitcoin as their currency
5) Public keys, private keys, QR codes, and technology like “Minting”, “Staking”, need to go away. It is currently too difficult and scary for someone with average technology knowledge to use comfortably for serious transactions. Think mobile app that requires no skill and it just works.
6) Small country with high inflation rates starts using Bitcoin as means to pay for food/goods/services
7) Major retail stores start accepting Bitcoin for payments

What do they do with the mining pools once they take over?

First, Turn off the miners. This is a very temporary attack and just means the BTC network is slow for a while and takes time to recover. A big deal, yes, renders BTC relatively unusable and tanks the value for a while. But despite all of that, the BTC network will say "never again" and learn the lesson of requiring geographically diverse pools. We might have to experience this before we fix it, but it won't kill BTC, the true ownership of keys and decentralization, which still exists despite the network being slow, will be resilient.

Second, Attack the network. the BTC network follows specific consensus rules, you can't go against those even if you control the miners. the other option is to re-write history, to do some transactions, spend some money, and then go back and re-write the Blockchain with "bad" data. This would undoubtedly suck, it would be very bad public relations for all crypto-currencies and laymen would not trust Crypto for another 10 years, they'd declare it dead over and over again until people finally admit it isn't dead.

I don't think so, but if bitcoin goes to $3,000, that would still make bitcoin’s price massively valuable. Remember, bitcoin was at $600 for most of 2016. That means that it spent years after the first bubble at 2x below $1,200.

From the perspective of 2015 and 2016, $3000 bitcoin is just a massive increase in price. This is actually a critical point which I think a lot of people, permabulls and permabears alike, don’t understand. Bitcoin can go to the lower $3,000 and still have demonstrated a massive long term price increase. It just depends on your timeframe and comparison.  if you think bitcoin is undervalued at $3,000, it’s not that bitcoin is actually undervalued, you’ve just been spoiled by $20,000 prices. after all, it is impossible for Bitcoin not to gain value over time by this mechanism as long as it stays secure and a fixed supply asset.

I'm really influenced with the agent-centric approach of Holochain as a framework for dapps, and possibility a new internet. Conceptually, this is the only project that has surprised me in the way the Bitcoin and Ethereum whitepapers did. Separating the distributed and decentralized aspect from the specific data verification mechanisms, allowing for "sufficiency" based on importance/value of the data from fully permissionless to Blockchain level consensus/security, seems like the best approach to creating scalability, distributed, and decentralized internet. it gives us good ideas to model changes to Ethereum. Very interesting project, wish they success.

I recommend everyone to pay attention to Verus. An interesting project, and the team has many plans. this company is definitely waiting for great success, and advise everyone to consider this company for themselves. it has developed a lot of leading technologies, including its Proof of Power 50/50 PoW/PoS consensus, CPU-friendly FPGA-equalizing, quantum secure hash algorithm, and a number of other solutions previously considered virtually impossible to solve. Most recently, the Verus Project started publicly testing its next major upgrade, which realizes the vision from the Verus Vision Paper of public blockchains as a service. Right now on testnet, you can easily create and fund new blockchain currencies yourself.

It not only provides/activates financial freedom for individuals but also governments. There are different countries which were sanctioned by the USA and European Union, and it's apparent that they don't have a choice but to use cryptocurrency as the primary monetary instrument. Due to the hyperinflation such countries like Venezuela, Iran, Lybia were left off by themselves, sanctioned, and without any possibility to drive their economy forward. It's a bulletproof fact that Bitcoin may play a signification role in the development of these countries. I wish more people understood that Bitcoin is about freedom and not about Lamborghini.

Exchanges execute Orders/Prices on their own platforms, they are not in sync with other exchanges. It's the reason arbitrage trading exists , means buying cheaper on one exchange because it's there is profit to sell on a other exchange. Every exchange is used by different people. it has different volumes, buy and sell orders, and different hours with the highest volumes. CoinMarketCap and other cap sites only report on them, and usually report averages. The only "real" prices are on exchanges simply by supply and demand. Basically never trust coinmarketcap for accurate price action, especially for Shitcoins.

ATM or just buying from an ATM is not adoption. adoption will be spending BTC on everyday purchases or it manages to becomes a store of value such as gold is. These ATMs have super high fees and majority of these fees go to the person who purchased the ATM, they only exist to make money for the person that owns them. they can be useful to educate people anyway so that they stop being frightened of Crypto. many people have heard of Bitcoin so having seen this ATM they will realize that it something "usable" and perhaps will want to learn more. Not that much of adoption but in sight.

The much bigger concern is breaking military and commercial encryption that doesn't hash public keys. Bitcoin addresses are naturally quantum resistant because the public keys are hashed several times to create the addresses, and the hashing function is not endangered by quantum computing yet.

While an attacker could use a quantum computer to derive your private key from your public key, your public keys are not revealed until your bitcoins are spent. As long as addresses are not reused, the only time your bitcoins would be vulnerable is the brief window between the time your transaction is broadcast to the network (revealing your public key) and the time it is confirmed by a miner. This is one of the reasons why modern wallets issue change to brand-new bitcoin addresses with new keys.

Once you send bitcoins out of an address, you ought to never put bitcoins back into that address ever again. If you do, then the attacker might already know your private key and could forge a transaction to steal those newly-added bitcoins. Best practice is to use a new randomly-generated address every time you receive bitcoins, and let your wallet application manage all of those addresses for you. In summary, Addresses that have not been previously used in spending transactions, burned bitcoins, and unintentionally lost bitcoins, are not vulnerable to quantum computer attacks.

I'm hopeful about Cryptocurrency, and right now Bitcoin is the only real token to hold. the true capabilities of Cryptocurrency are barely comprehensible. For me it's the ability for transactions of immutable value to be made across the globe instantly and direct. Right now if you think about how you make payments today, they all include a third party to function, even if you consider cash withdrawal from your bank account. Being able to send directly allows not just individuals, but entities and even software to interact with and control units of value.

Once we understand this we can start building use cases that have never been possible before with the backing of the global internet networks, beyond just the Cryptocurrency network.

I think people obsess far too much about 51 percent attack. it has some kind of attractive mystery to it that distracts people. If you're worried that someone might reorder history using a high hash-power collusion just wait longer before you consider your transactions final.

A far bigger risk to Bitcoin is that the public using it won't understand, won't care, and won't protect the decentralization properties that make it valuable over centralized alternatives in the first place. a risk we can see playing out constantly in the billion dollar market caps of totally centralized systems. The ability demonstrated by system with fake decentralization to arbitrarily change the rules out from under users is far more concerning than the risk that an expensive attack could allow some theft in the case of over-eagerly finalized transactions.

If you are just starting off, I would probably suggest using Coinbase as a learning platform. It has a weekly limit for new accounts so if you aren't familiar with trading and fees, you can put in some money to test the waters as it's not a huge sum to profit or lose. The fees are a bit higher, but you can use a credit card to make instant purchases and the verification only requires a valid driver's license. Took me about 5 minutes for the verification to complete. another option is Binance that allow unverified user to withdraw per day, so it might be a good place to start. I recommend not touching Bitfinex with all the Tether FUD going on, and avoid Bittrex as well.

Getting mixed feelings about it. On one hand it's really good that they cannot stop bitcoin, hence the silence. they can stop centralized Libra, hence the swift action. At the same time, Crypto success depends upon mass adoption and mass adoption means people being able to use it without fear of sanction. Most people will not risk breaking the law to use Crypto, therefore no mass adoption, therefore Crypto cannot succeed. France & Germany are more worried about Facebook, a corporation that is arguably more powerful than many governments, taking control of their financial system. If Libra became the world currency, Mark Zuckerberg would be the most powerful man to ever exist in the history of the world.
