It's because BTC was the first.

Ethereum is what has risen coming of it.
Think of it like this is what Ethereum will be known as

Bitcoin price rising in this time due to the popularity of bitcoin self, and so many hype now. You can see and no need technical analysis for this, lots of people turning into hypebeast and buy bitcoin massively although these people do not know about bitcoin and cryptocurrency. That's why the bitcoin price keeps going up.

I think the best reason behind why bitcoin is still on the top because they know what the needs of their market are.
They know how to adopt and improve themselves in order to provide  a excellent quality service from this many investors are trust and loves which leads them to become number one.

It a great thing that you see the bitcoins in crypotocurrency is dominating.
The reason behind why the bitcoin is rising up because of their strategy that focusing on how to satisfy the demands of the investor through this they can be able to get a huge demands that will support their services.

a good statement, and I agree with you.bitcoin always makes everyone confused and disbelieving. within a few months bitcoin was able to reach a value of $ 18000 more, but today is still down.
and I'm sure, more people will invest in bitcoin, so bitcoin will increase.

I concur with other views of it being the first in Crypto, but the elephant in the room is, that Bitcoin is an asset class/ store of value dare i say like gold bullion.

You invest in gold for the future and to store in your portfolio should you require it at a later date.

When you cash out your gold, sure you need to take it out the safe, call the mint then line up then pay a fee to convert the gold to fiat.

On the other hand you can just walk up to an ATM and draw out the same money a lot faster and buy what you want in an instant.

Its the new gold for the public at large and a store of value for us <100k block height miners investors long time holders.

Although that is not what Satoshi wanted it has become the default store of value globally.

Its in demand and by a wider community now than 3-4 years ago where it was purely the domain of the programmer devpc nerd.

Its demand wont stop, sure it might wane with the FUD out there but it has by far the most believers in the crypto world.

Belief in Bitcoin is a powerful thing, without it we wouldnt be having this forum or this discussion and it would have disappeared with the EverQuest Platinum of years gone by.

I think the reason why bitcoin rising it is because of rising community of bitcoin user also it become popular in many country. Therefore bitcoin will still rise even there are fluctuating in price, also because of the rising value of bitcoin many people is become much interested to it.

Many people questioning the excellence of bitcoins in our industry.  In fact they are still number one and successful along its journey in cryptocurrency. 
The reason behind why they are still number one and rising so high is because of they are flexible and always innovates their system in order to meet and achieve all demands of their investors. 
The bitcoin always focus not on profit but on how to satisfy each demands in order to have a good feedbacks.

Yes, and bitcoin will continue to rise for the years to come, I think the reason for that is that bitcoin has not yet reached it's market, today only about 10% of internet users knows or used bitcoin, this suggest that bitcoin has so much room for expansion, and with fix amount of bitcoins in circulation, an increase in demand means increase in price.
