To be honest, I don't see much potential in other coins than Bitcoin. Don't get me wrong I do not say that alt coins are bad but they just won't be accepted on a high scale. Even Bitcoin is not accepted everywhere and implementation costs are high.
Nevertheless I still keep some alt coins but it's mainly for a quick buck.

Problem is that most business owners are to lazy to implement Bitcoin. They won't miss much sales when Bitcoin is not an accepted payment method. So volunteers (Bitcoin supporters) need to explain it's value, potential and implement the system. If Bitcoin gets more populair under business owners they will probably hire someone to do it. I just don't see this happen for 20 other coins.

The real problem for businesses is bitcoin price volatility. They work with USD and are happy with it.
They just look at it that it's too much tention for them to accept a form of payment that doesn't go with the rest of the business.

I mean even if they accept crypto, they still need to buy goods with USD. What if btc price goes down at time of buying ? Then that's a loss.

That's why they just ignore the whole crypto thing.

seem to me that the bitcoin is the mother of all coin and altcoin is another branches of cyptocurrency world against bitcoin. bitcoin is head coin and eth, etc, ltc, doge, and so on are alternate currency of bitcoin.

Most of the altcoins are just copy paste of bitcoin and there are still more altcoins which are just copy paste of other altcoins since there's no restriction on creating a new coin every other person has their own coin. No wonder there will be a time when even you and I will develop our own coin like excubercoin, adbitcocoin etc and will be coming up with an ICO. So actually everyone is finding it to be an opportunity to earn as much money as they can when the cryptocurrency is a boom and flourishing, everyone is leaving no stone unturned to cash in on the opportunity of making huge money by coming up with a new coin. Because of this tendency most of altcoins don't seem to have any future but since bitcoin is original and in fact the pioneer and the root out of which all these altcoins came into existence and most importantly bitcoin has a huge number of supporters and a huge community bitcoin has a very good future. While most of altcoins die after some time or remain confined in one or two fields where they find application or their use bitcoin will remain there forever as it's global and has a mass appeal.

Me too I don't see altcoin like what I've seen in the bitcoins before. They do not have that kind of potential that bitcoins have. But there is some altcoins that have value like ethereum which is having a good price in the market but not as good as what bitcoin can give to us. I think bitcoin is still and will still be the best cryptp currency in the industry.

Other than bitcoin the altcoin market has all sorts of crypto coins with their special uses from those that can be used for insurance purposes, others have a sole purpose for gambling, others altcoins are used to obtain some marijuana so on and so forth... it all comes down to whatever floats your boat.   And from my observation most people use them for trading/investment holding to earn some extra cash.

Ethereum is catching up. I read various negative headlines about it but I don't know if these issues are enough to put ethereum off the crypto map. Business competition is healthy. We can see a rabbit vs turtle marathon between these two cryptocurrencies in time. In fact, I convince some of my friends to support ethereum in DENT ICO. They join the tokenizing activity at detcoin dot com.

Many of the so-called altcoins have no real potential. Of course, there are a few who have good value and are patronized by a certain community while there are those which are plainly categorized as shitcoins. As of now, it is still about Bitcoin. Many holders of altcoins are just in for the sake of possible quick profits.

But then again, there is an open space for any coin here and it is all up to the market how it would receive and utilize the said coin. Right now, we are abuzz with new coins almost everyday. I don't if it can be good in the long run but am waiting for the possibility that the market would just close its eyes to this kind of introduction barrage.

This issue can be solved by making a system that automatically exchanges the Bitcoins for the best fiat offer.
However this won't give them the 1:1 rate and will cost money to implement.
This means there have to be extra fees for Bitcoin payments or the owner of the business is a fan of cryptocurrencies and doesn't care about temporary eventual loss.
