BitCoin is a great start as a thought of a new currency, and it's the most widely accepted and used digital currency to date, but that doesn't mean it is the best for everything.

BitCoin is extremely slow, taking 15 minutes for a transaction to confirm. There's other problems as well, but this is about alt coins.

Altcoins, at least some of them are actually very useful, some of them don't relate themselves as a currency as all and they utilize the blockchain.

I think those people that bash altcoins here don't understand crypto too well. There's room for many markets, and it's not all about BitCoin anymore. I think altcoins are good because they bring in people who use bitcoin to exchange for altcoins. That's gotta be good for business, especially for the exchanges.

Altcoins could be faster than bitcoin, they could also provide extra layers for security. Whatever the thought, you can create it on the blockchain.

Actually bitcoin don't need any altcoins, the altcoins just use the blockchain(clone or just the idea)...

I think it's good because people can choose what coin to use, if they are loking for something more fast or more anonymous..

Bitcoin were the inspiration for several altcoins some of them has just improved and has several things we do wanna bitcoin to has, but sure bitcoin is the king, but if it fail, some other altcoin will replace it, there is several money into bitcoin, and people dont wanna and will do almost anything to avoid bitcoin fail.

If Bitcoin has no rival like alt coins then the price of bitcoin must be very high today. The trade market will only have bitcoin and every countries flat money. Besides those alt coins are created to beat Bitcoin. But there are some alt coins that has a unique road map that inspires a lot of users to use the alt coin.

Whatever rate a alt coin may have but it would still not be compared to bitcoin i guess, because alt coins are mostly traded just to generate more bitcoins out of them and that is the reason why alt coins are getting so many users as well, just because of bitcoin.

The role in Crypto currencies is in bitcoin only... but all other alternative currencies play a good role for traders as they help traders to earn more bitcoins using them... otherwise bitcoin can stay the same even without alt coins but alt coins will start dying if bitcoin starts dropping its price...

bitcoin without altcoins still good survive and will be the best payment method
whereas altcoins without bitcoin cant alive they still needs bitcoin
without bitcoin, never will be crypto exchanges, trading crypto activity

Bitcoin is a currency and none of the currency depends on any other currency, but their strength is depended on its rate of adoption by the people and its regular circulation among the community. The more people accept it the more strength it adopt. So bitcoin is independent to altcoin or any othe crypto currency.

That is true that bitcoin is independent from altcoin and bitcoin alone I think can survive as long as there are supporters who used it. Bitcoin,the father of all crypo's is the standard in cryptocurrency.But an altcoin,from its name alternative coin, is really an alternative one.

Bitcoin is traded a lot against altcoins in many exchanges.
If suddenly that demand would vanish, we would have an over supply of bitcoins on the market and that would lead us to a drop in the bitcoin price.
Of course bitcoin could survive that scenario, since it pulls its strength out if the infrastructure built around bitcoin, but it would not be pleasent.
