there are only 2 forks, SegWit and SegWit2x. the first one got everyone's support but the second doesn't have as much.
the bitcoin cash is just a split off to make a new coin like many other altcoins that have done this before. this is technically the same thing.
the nChain is not really a fork, it is something that was proposed for scaling, I don't know how serious it even is.

and any fork can happen at any time. nothing is stopping anyone from forking from bitcoin. you can do it right now too. you just need to have a little mining power and the knowledge of how to do it. these forks will become something only if they get the enough support

altcoins rising price never had any significant effects on bitcoin price. they usually have the opposite effect of what you expect actually. because when they get pumped (BCH was pumped about 90% last day) they give their traders a lot of profit and all that profit comes back to bitcoin in the end and pushes the price even higher.

now I know what this is. an advertisement for a new ICO
no my friend that is a pointless thing to do. you can not just come up with some abstract idea of a real world application and make an ICO out of it just to make money. that won't work.

the only good advice is to never listen to random people!

it is a common thing in the world that people spread lots of bullshit around and when they come online this becomes more severe. and when it comes to bitcoin things become even worse. there are a lot of FUD, a lot of people who don't even understand what the hell is going on but they have a hot opinion about everything.

this doesn't mean you shouldn't use what some useful people say, you need to gain enough experience to be able to first make your own decisions and second figure out who is just FUDing and who has a point.

it seems a lot better than all the other alternatives for a web ethereum wallet. but I kind of find it weird that they don't even have a block explorer for ethereum but they added its wallet! I hope they add the explorer soon too, it is very useful and necessary to have with this type of web wallet.

the good thing about it is that you will control the private keys and won't be like Coinbase. and also you won't have the headache of dealing with horrible ethereum wallets and their bloated blockchain which is much bigger than bitcoin's.

here is the link by the way: https://blog.blockchain.com/2017/08/17/blockchain-wallet-adds-ether/

true, and I am not denying that fact either. it is good to take some profit out each time there is a huge rise and when that rise is super fast.
but to think just because price is "high" that means it will fall to oblivion (according to OP down to $900) is pretty dumb.

as for your "something goes wrong" statement I have to say, nothing is different now, something could go wrong any second of the last 8.5 years and will be the same in the future. and most altcoins (including bitcoin cash) share many things with bitcoin and if that something goes wrong with bitcoin it can by extension go wrong with them also.

this is more scary than interesting in my opinion.
we have two identical crypto as far as mining is concerned and the miners can switch at any moment they wish to. with lower difficulty a higher hashrate can produce a large number of blocks in a very short time and that can harm both cryptocurrencies at once, and mostly BCC

imagine a miner who finds 40 blocks per day in bitcoin switches to BCC and mines 1000 block in 1 day with a low difficulty and switches back to bitcoin the next day. (extreme example so you get the point)

the reason why no altcoin has so far "defeated" bitcoin is mostly because none of them are doing what bitcoin (a decentralized cryptocurrency) is doing any better.
there are many innovations and many altcoins copy of these innovations, but none of them have yet been able to fix any real problems and achieve the real adoption in the real world. they all exist on exchanges and are treated as a virtual thing with no real world usage so far.

Um, maybe you haven't been around because your account is old enough as a hero member i can't say you are new to bitcoin! everyone knows the reason already. it is not really something weird.

the scaling debate has ended and all the uncertainty went out of the window when SegWit reached the 100% support. before that, everyone was either scared, uncertain or both. so they were hesitant to invest in bitcoin. and so far bitcoin is still the same decentralized cryptocurrency that nobody can control and also has a very small and limited total supply.

and now all those people are coming back, knowing that issues are solved and there is only upwards to go.

I have been using bitcoin for a couple of years now and I have been around since the $200 price and each time there is a rise in bitcoin I see someone like you create a new account and say the same thing about that rise being a bubble, warn about holding, and generally the same things you just covered.

and if I wanted to listen to you people each time you create a new topic like this then I wouldn't have had this much bitcoin by now. and I will continue ignoring this type of FUD in the future and use my own brain to make decisions.

bitcoin is the most valuable thing with the biggest potential that most people don't even start to understand. what bitcoin does and what it offers combined with the scarcity means only an idiot doesn't hold bitcoin until 10K dollar at least.

the only free wallet that you can have and be sure that it is 100% safe is a paper wallet. if you don't want to pay just go with paper, it is not hard to create and it is not hard to secure. make backup(s) from it and then move your coins there. you can always add more to its balance each time you buy more bitcoin. but when you spend from it just make sure to create a new one and transfer your coins to that new paper wallet.

you can use bitaddress for it.

don't confuse the security of a wallet specially a web wallet or an online wallet and the security of a third party service like exchanges with the security of bitcoin.
the former is just people's mistakes like not having a cold storage or having a malware on your computer that steals your private keys and with it your bitcoins. the later is directly related to bitcoin. and it means without it bitcoin can not even exist. and it is easily achievable too. just by following certain security rules, such as having a cold storage or simply buying a hardware wallet.

this is the worst suggestion at this current situation of altcoin market!
we all know that altcoins are getting dumped these days and yet you suggest an investment in the top 2 dumped altcoins (ETH and XRP)!!! investing in either of them means a very huge risk of losing a large percentage of your money while having a tiny chance of keeping the same value or increasing a little bit.

and don't even get me started on new ICOs they are worse than investing directly in altcoins. the risks alone means you should stay away unless you are a "gambler" not an investor.

it is not a stupid question it is just a weird one! and in the wrong board!

you found some random addresses that got some deposits in them. it is a common thing, if you look around on the blockchain you can find hundreds of these nearly the same size. people move their coins sometimes. it is sometimes the old users who have coins from when price was really low ($20 for example) or from services that have been around for years (like btc-e for example) and they are moving either to sell or pay their customers from cold storage or just simply trying to claim their bitcoin cash reward.

in short this is very common and is happening almost every day.

I don't know what "sale" it is you are talking about but according to the charts and history ethereum price was 0.01BTC when it was listed for trading back in Aug 2015 and now it is 0.07BTC which is a 7x rise
even if you take the USD price of it that is still about 100x rise.
bitcoin on the other hand was about 1-10 cents when it was first listed for trading on exchanges. and now it is $4000+ and that is a 400,000x increase in 8 years

oh and by the way ethereum market cap is 27 billion because it has 72million coins premined and we use price as an indicator not the market cap.

this is very true. bitcoin is not a pump and dump altcoing like ethereum. which is why bitcoin won't give you 1000x return in a short period of time and then start getting dumped like what ethereum is doing. and by the way it was 10-13x not 1000x you are confusing what x means versus what % means

instead bitcoin is profitable in the long term because it has real world usage and it is in fact being used as a real currency. which is why the adoption for it increases over time and with it, the price goes up. a solid price rise.

with pump and dump altcoins such as ethereum, the pumping team start their fake pumping operation and push the price up to fake numbers and then because there is no real world usage and it was all a hype and a bubble, it bursts and the price falls down hard.

oh and by the way it is not just ethereum, it is every single altcoin out there that can give such profit in short term when they get pumped

NEO has been falling for some time, you should have sold on the top or at least when the drop started and then if you really believe it will go up to $500 and not just saying a random number, then you should have bought at the bottom again and have more NEO tokens.

this is the trading board after all, not the holders board.

LOL, it is the first volume now on bittrex with about 3 times more vol than the next!

no they are not, they are selling it for now, and as I said above they get ready to buy at the bottom.

yes, I saw the potential a couple of days ago and made my investment and have already taken my money+profit out of it. I believe it has good potential instead of ETH and has room to grow more too.

SegWit2x is not a who, it is a what.
and what it is, is a proposal for scaling bitcoin. it proposes that after activating Segregated Witness we also increase the block size to 2 MB instead of the current 1 MB block size.

it is also known as NYA (New York Agreement) which was an agreement between miners (about 80% of them) and some businesses. and so far it has enabled the SegWit part through BIP91 and is scheduled to do the 2 MB hard fork within 3 months.

here is the link to the source code: https://github.com/btc1/bitcoin
here is the link showing the miners' support for it: https://blockchain.info/charts/nya-support
here are 2 good links explaining it:
https://bitcoin.stackexchange.com/questions/54728/how-is-segwit2x-different-from-segwit
https://www.coindesk.com/explainer-what-is-segwit2x-and-what-does-it-mean-for-bitcoin/

doing both at the same time is the most profitable. here is how I am doing it anyways:

initially I buy bitcoin any time that I have any money to invest, it doesn't matter what the price is. it can be $1 or $1 mill. I believe in the future of bitcoin and I will invest as much as I can. I am also earning through different ways and will hold all the earned amounts.
this is the holding part.

now the trading part:
I have dedicated a portion of my total bitcoins for trading. this is mostly trading altcoins but from time to time when I like bitcoin market and it is at its most predictable I engage in bitcoin trading too.
what I do is I buy altcoins that are rising (getting pumped) or have a good future like litecoin and sell them when they went up. I do all my tradings in bitcoin/altcoin markets not fiat. and in the end all the profit will be added to my bitcoin stash.

in other words I buy bitcoin then multiply what I have to earn even more profit.

I can't really give you a percentage. and it is wrong to say it based on your salary, you should consider it as a percentage of the "remainder" of your salary after costs.
for example if you have loan payments, groceries, bills, ... you pay all of them and what remains you have for investment. from that amount you decide how much risk you are willing to take on that amount. then come up with your percentage.

for example if you get paid $1000 and your expenses are $800, your investment amount is $200. now if you want to take big risks, you invest all that $200 in bitcoin. if smaller then you invest $150, $100, $50,... in bitcoin.

as long as this leads to more decentralization of mining throughout the whole world, it can be the best news for bitcoin. so far we have only China as the major manufacturer of mining equipment known as ASICs and they can do whatever they want, like asking for high prices, not releasing new version of their hardware to other countries until they become older, .... but if other companies start mass producing that can create competition and it is good for customers.
