the only opportunity that the altcoin pumps give you is if you are a trader who is willing to short them otherwise there is absolutely no opportunity in a dumping market except a lot of losses.
don't get fooled by the lower prices because of dumps they are lower but not low or lowest. and that is the important part.
additionally you always want to buy an altcoin that is going to rise soon not an altcoin that is dropping and may not rise for many months to come.

you should go check the market on daily basis and then look for an altcoin that is building up towards a pump. if you can find such a coin then invest in it and enjoy the pump as long as it lasts (which can be a couple of hours to a couple of days) then dump it as soon as you reached your desired profit percentage and get out to have money to do the same thing from scratch and consistently increase your wealth.

to add to what was said, generally speaking bitcoin and all of its copies (forks) share the same mining algorithm. so if you have equipment that can mine bitcoin you can use it to mine any of the copies too.
that means a miner will look at profitability of different options of mining. if one option is more profitable then they will switch. that is the biggest problem that these forks are causing and also the relationship that you asked about.
but this problem is usually short term as these altcoins (fork/copies) are not sustainable in the long run and as they get dumped, miners switch back to bitcoin.

so far there has not been any hashrate drop for bitcoin which means nobody has switched!

most of these altcoins had a small recovery after they got dumped which is why you are seeing a smaller red number in front of them. but in fact they all got dumped a lot bigger than bitcoin price drop.

the reason is probably because the whole pressure was on bitcoin to crash it and it still has not gone away so it is impossible for it to recover.

if you can not handle a small fluctuation in bitcoin price then you should never invest in bitcoin because that is what you will always get, fluctuations. and they are perfectly normal.
expecting price to drop down to the ground just because it dropped a little is just dumb. it is as dumb as thinking it will go to $10 million just because it increased a little.

well for nearly as long as i have been on bitcointalk i have also been warning others not to bag hold altcoins aka invest long term and have portfolios! but nobody listens to the warnings so here you are losing money as the altcoins always go down in the long term making you lose what you have invested in them.

it is not too late though. you can still learn from your mistakes and start being more realistic in this market and learn how to trade it for maximum profitability.

the technology can never die. and with the daily growth that bitcoin has you can be sure that it will never die and bitcoin will only get stronger every day even if you don't see its price rise every day.

and as bitcoin gains more strength and introduces newer technologies to the whole world the whole cryptocurrency scene becomes stronger and grow more.

i disagree.

altcoins must be bought when they are being pumped not when they are being dumped. and right now the altcoins are getting dumped and they have no pump coming to them for a very long time. some of them probably never going to get pumped any more.
so buying now means buying bags of worthless crap that will probably lose more value but surely will take a lot of time to give any kind of profit.

that doesn't sound right at all.

first of all everyone in bitcoin world knows that Bitmain (Jihan Wu) has the highest hashrate in the whole world which is dedicated to bitcoin and bitcoin cash. and majority of BCH hashrate (more than 90% of it) belongs to Bitmain. and BCH is turning into BCH-ABC which means it will succeed without any "war"!!!
bitcoin-SV however has little support and little hashrate with no giants like Bitmain so it is bound to either fail or exist with minimal hashrate. unless they can pump it ridiculously high so that miners willingly go there for the profit alone.

hypothetical death of bitcoin means death of all the altcoins because majority of altcoins are based on bitcoin even if it doesn't seem like it at first look. and also because they all exist because of bitcoin! most of them have a value thanks to bitcoin traders who want to increase their bitcoin. so if there were no bitcoin they would also have no reason to trade those altcoins either and they will all die.

the true believers of bitcoin are the silent type. you never see them advertise their beliefs or the amount of bitcoin they own. there is no reason for that. they are simply accumulating more and more bitcoin before the big bang happens and we reach mass adoption.

the noisy ones are always the short term traders who are trying to earn "fiat" using bitcoin.

it is not limbo it is accumulation phase. and if you take a look at the market you can clearly see that the whales accumulators are hard at work buying bitcoin at the  current price and keeping it from rising up. each time they place sell orders on top to prevent the rise for the time being. and that is all pointing to a signal for the upcoming rise.

no you should NEVER invest in coins only because of their ranks. mostly because ranking system that websites such as coinmarketcap.com are using is a broken method that is falsely ranking shitcoins on top.

basically when it comes to altcoins my approach is analysis of their market instead without paying any attention to their rank or even name!

also based on my experience i have to say i have made a lot more profit from unknown small coins that i have ever made from top rank coins!!!

most probably i would never touch this coin mainly because it is centralized although it is not the worst kind of centralization since there is a government behind it instead of a shady company with unknown people who are obviously scamming you!
but this coin exists and their government have been advertising it a lot and have been trying to make it bigger. i have yet to see the price and its market though!

some countries have not yet had any clear rules and regulations for cryptocurrencies so far even though they have been growing in their country. so some places such as Thailand need to act fast about it and start with more regulations so that they can keep the market and flow of money under control in order to prevent fraud and also lots of illegal activities such as money laundering for example.

no i don't think so.

there is a very good chance that if the global financial system collapses we see at least 90% of the altcoins die within the first week and the rest of them also take a big hit to their prices as everyone cashes out to get their precious money out so that they can put it in something with a lot less risk.

don't forget that altcoins are considered super high risk investments and generally people always run away from high risk investments in face of crisis.

i don't really get how you are trying to make a conclusion based on things you said here.

the current state of the market is not deceiving at all. it is only strange to people who are new to bitcoin and are lazy enough to not check the history of bitcoin. in the past we have had a lot of situations like this where price drops after a fast and big rise and then it becomes stable like this before it starts rising up again.... and that is normal.

that is only your personal perspective not what bitcoin is really about. and unlike what others say i don't think it is the news fault. it is your fault for only focusing on part of the news that is negative. otherwise there is a lot of positive news too. for example the news that is about millions of merchants accepting bitcoin all around the world and increasing their revenue and security.

your mistake is that you think the investors are choosing between bitcoin and others so your conclusion is that if the "others" are more then smaller number would choose bitcoin which sounds logical but your initial assumption is wrong which makes the conclusion wrong.

what REALLY happens is that people aren't left with multiple choices. they only have one choice and that is bitcoin. AFTER that they have many choices between many altcoins and they have to decide which altcoin to choose to invest their bitcoin in and make profit on it.

no, no altcoin is worth "investing in". on the other hand all of the altcoins have the potential of getting pumped so they all are worth "trading". and there is a big difference between these two.

if you look at each and every altcoin out there you can see that they have gotten pumped at some point without an exception so they all have the potential of giving you profit but that is only potential that doesn't mean you can make profit. you will succeed only if you are familiar with how to make profit from a pump and dump.
