Many of the Altcoins turned out to be either projects with no future or outright fraudulent schemes. As a result, altcoins are mostly the cause of losses among investors, because, in addition, they take away attention from bitcoin.

Most altcoins have had and still have millions of market capitalizations, meaning that representatives of the cryptocurrency industry have invested enough money in them. Of course, redirecting these funds to Bitcoin would seriously change the current situation with the Bitcoin exchange rate.

For example, projects such as Auroracoin, Paycoin, The DAO, and Bitconnect ended in either failure or a fraudulent scheme. The fraudulent Bitconnect project ceased to exist in 2018.

There are really a lot of "useless" altcoins in the cryptocurrency industry. They attract investors with the possibility of quick earnings due to the relatively high volatility. However, most often altcoins with low capitalization bring only losses and frustration to newcomers in the industry who do not have time to exit the project in time and find themselves in the red.

You are overthinking things, except for those that are invested in XRP most of the community does not care, in fact before the growth of XRP during this year and its ridiculous pumps in price the coin had remained still for a long time so many people forgot that coin even existed.

So it is a mistake to think that just because XRP is doing weird things that somehow this is going to discourage bitcoin investors, the reduction in the price we are seeing right now has to do with the fact that as soon as we reached a new all time high people got scared and began selling their coins because of it.

Altcoins can't affect the Bitcoin price. The most dominant cryptocurrency in the market is Bitcoin. However, Bitcoin can affect altcoin prices. We have seen so many cases that Bitcoin did this. As long as Bitcoin stays the most dominant, I think it will continue to be like this.

I think no, there is no harm for bitcoin if the altcoin price up. Can you see the marker correctly? Because in my opinion all altcoin price market will be pumped when bitcoin price is already pumped. I mean, most investor will trade in bitcoin only when bitcoin price getting pump so as it will affect to altcoin price thaf will be dumped a lot. And when bitcoin price meet a sideaway market the investor will pump some altcoin. As you can see there is no altcoin who successfully reaced the previous all time high, if you found it can you tell me. In this bull run market I suggested you to trade or invest your money in bitcoin only.

When Bitcoin falls, altcoins tend to fall as well. But the market responds by slowly raising Bitcoin and the other coins. Fortunately we see a recovery in them. Regarding XRP, it reached its highest peak of US $ 3.40 on January 7, 2018. Since then, the price has remained below $ 1 despite leading the 3rd place in the crypto market.

No, I don't think that can make the entire industry a scam because people will think about which project or coin is a scam and will not invest or buy it. I think people now become smarter than a few years ago, and they will search for the right news and not join in the project that they don't know or will not invest in the coin that they don't have much info.

As far as I know Bitcoin will not be affected by rising altcoins prices, because usually altcoins prices are affected by Bitcoin.
Moreover, when trading altcoins, usually use Bitcoin pairing, so the Bitcoin price increases. I have not found any increase in
the altcoins price to affect the Bitcoin price.

only one coin pumps 100 percent and all industry will be a scam ? haha . i will believe if he says that all coins pump 100 percent because thats more questionable but one coin that pumps a hundred percent shouldnt be easily judge as a scam but take a look if what coin was that and take a research about that coin if you see a positive  news behind it then that was a legit pump .

p.s :  if btc pump 1000 percent will you guys say that it was a scam ? fck it , scam or not ill still be happy because i can be finally rich if that happen

Most of the altcoin trade volumes comes from trading between altcoin-bitcoin pair. Only a minority comes from trading with fiat currencies. Under such circumstances, it is natural that an increasing market share of altcoins may negatively impact the Bitcoin market cap. However, during the current rally, Bitcoin has remained strong, with more than 62% market share (back in 2017, during the rally it was less than 40%).

Hahaha, you're right. I think he gets a scam from one project, so he says that all are scams. I don't think they will say that bitcoin is a scam if the price pumps 1k% and they make a huge profit from that. But for people who buy bitcoin at the highest price and not having a chance to sell it again to another high price and just hold it will say that the bitcoin is a scam. That is because they are getting trap at the highest price, and it is hard to manage their losses.
