Fundamentally speaking the whole problem with these bitcoin fan boys is that they are not able to come out of their shell and consider something new that might challenge their investment in mining.
They will downplay any “alt” since it challenges bitcoin.
Bitcoin is a great start but not a good long term solution. It started something great but of late its been showing weakness and those weaknesses are not easily solvable.
First and foremost bitcoin replaces traditional currencies and one can argue that currency is itself a dying concept. So bitcoin, in my opinion, is a last ditch effort to save currency and so far it hasn’t shown that its done a good job at that.
The transaction times are taking longer and longer.
The fees are getting higher and higher.
The core dev team can’t work on a consensus to fix the block size issue and how can they without disrupting the whole bitcoin network.
The founder is some unknown mystical personality.
It continues to get bad press.
Banks don’t like it.
VC money is going down.
Mining is being controlled by only a few people.
If you build a smart contract system based on the btc being the token then the above mentioned problems still exists.
Ethereum on the other hand is promises something that no one has ever gone before. To summarize building distributed applications on a world computer for distributed autonomous organizations with ether being the fuel of the network. Oh yes and I forgot .. dynamic block sizing based on gas points.
The ethereum network has just started and it will continue to grow and invent as we have seen with the roadmap with different types of blockchains providing different levels of redundancy.
They have shown their ability to change with the recent hard fork primarily because the miners are on gpu’s and cpu’s and can adjust to the new software.
