So, I quoted your post because I would like to ask; Can you highlight precisely some of these many bugs bitcoins has? May be the core devs can fix them. I think that you would like to say that bitcoin has differences with altcoins which is indeed true. One of them I would like bitcoin to have is anonymity like as monero and some other alts but surely this is not a bug but a difference between the protocols of these two cryptos. But bitcoin has 'network effect' that means a vast user base compared to other alts. Hence, bitcoin without alts can survive but this does not apply to altcoins.

I just don't see how altcoins could even beat bitcoin while the majority of them actually rarely being used as an ordinary currency to become trading tools. And also, almost all of altcoins are now kept using bitcoin as their main currency to determine their value in almost every exchanger.
The most popular altcoin as for now I assume Ethereum currently have $1,209,273,138 and not even 1/4 of bitcoin's market cap.
From my opinion, that altcoin is not competitors for bitcoin, altcoin and bitcoin may work together to make cryptocurrency world even popular.

Bitcoin without altcoin? Then i could say bitcoins price would really high in value because people will only focus on bitcoin and not to other alts which we could able to see now but this thing wont happen at all since people or developers would create their own coin which will compete to bitcoin.

However, Bitcoin is only the prototype of cryptocurrency and I believe other cryptos have the mission to support Bitcoin. Moreover, some even stronger than Bitcoin and with the demand of traders, they can easily earn some profit with other currency. I just want to say that I appreciate what other people have done with altcoin and it is certain that one day, bitcoin will be replace by altcoin

That is right since bitcoin has been getting much attention and getting doubled every now and then, it has become really hard to mine so it became not profitable and the only option was for people is to find other ways to earn bitcoin and that is exchanging altcoins so without bitcoin altcoins wouldn’t be a thing.

in fact bitcoin is the main currency while people use bitcoin for trading alt coin and increasing their bitcoins. in fact bitcoin is a perfect currency and it do not need for any alt coin for its promotion.

LOL, Bitcoin blockchain is different from altcoin blockchain.  And what difference it is when you transfer your Bitcoin into altcoin (Bitcoin transaction is done here when you deposite in an exchange)  and then sending your altcoin to another exchange and convert it to Bitcoint (another transaction when you withdraw) and withdraw it?  Basically you are creating more transaction here unless you are sending your altcoin to an exchange that supports fiat currency altcoin trade.  FYI, this is not applicable in my country since our exchange only use Bitcoin Fiat currency exchange.  And lots of shop are only accepting Bitcoin( now how can you pay the goods with altcoin from my counry).

I think this is what hes trying to say, bitcoin without altcoins will be having the attention of millions of users to bitcoin. No other altcoin is available so the focus is all on bitcoin. So, the transaction of bitcoin will be every second and the bitcoin network will be very busy with all that transactions. Imagine a street full of cars and vehicles because there are no other street other than that.

Disagree and it's not like that.

Bitcoin price are based on people's buy and sell action, basically the demand. Bitcoin are mainly used for trades and different usages (money transfer, gambling, payments etc.) that's why it was bought by other people. If such cases that there is a price increase, it's not because of the altcoins. Remember the MT. GOX era or when bitcoin price were on the pump back then? There are only few alts that time that really a popular.
