I have a doubt , please only respond if you know what youre talking about . I beleive that bitcoin to usd price is stucked cause of all the alts coins that are pulling it down , if bitcoin rises an 20% againts usd , all the coins rise as equals. If bitcoin falls all the coins falls againts usd.
The vast majority of alt-coins have their value determined by BTC value. With the exception of LTC and a handful of other alt-coins, there's no direct means of converting fiat into these without having purchased BTC or LTC first and then exchanging them for the alt-coins. In other words, if someone wants to buy an altcoin,
they more likely than not will have to buy and sell through BTC to get there.
As with any other market, speculators will thrown down money in related commodities/companies/goods whenever there's a rise in the value of the primary item. It's possible that alt-coins are somehow impairing BTC, but I don't think this is a valid reason.
While its true that its traded on the pair you have to consider this. People are making profits off alt coins, people who buy or mine early some are making 1000's% profit. These people will want to realise some of these profits and thus sell some of the BTC they gain so what pepo is saying is certainly a factor. I mean look at black coin I made double figures BTC over two days, as did many others.
The problem with all these coins coming and dying is that people generally end up holding worthless alts and the big players and early adopters are already off with the BTC and likely selling some.
The bit in bold is not strictly true either, if you mine an alt early you can mine a lot with not a lot of hardware, yes I know that someone has to buy the BTC in the first place but the vast majority I would wager are investors BTC that they had previously, at least the people who are making money trading alts are probably general investors, I doubt too many people buy BTC to specifically buy an alt and if they do its probably to a large sum.
The original post in this line of question from Pepo.. seems to be a form of FUD-making and/or based on superficial mainstream propaganda.
Cryptos can both distract from and contribute to the value of bitcoin. Overall, the various alt cryptos have remained a fairly low percentage of the overall crypto market cap - less than 10%.
I get the sense that some of the developments with side chains will increase BTC's value - yet I understand that some of the competing cryptos continue to suggest that the side chains will NOT distract from the value of some of the alt cryptos. For example, the Ethereum project remains in full-swing - although maybe behind the scenes, the Ethereum founders will make adjustments to their going forward strategy(ies).
