I see many differences between bitcoin and ethereum.
I am not a bitcoin maximalist!
I see ethereum a solution for bureaucracy of financial branch. Bitcoin is more like a currency replacement then ethereum is.
Though, ethereum is more decentralized at network infrastructure and mining operations. Bitcoin is almost impossible to be mined by a single user and that will cause bitcoin to be centralize by a huge ASIC mining facility, at this moment is not a real threat but it can be in the future.
It is obvious what Satoshi's vision was, to be mined by individuals with personal computers, i think everyone agree with me that vision is not happening.
Ethereum at this moment can be mined without ASIC, and this is an important step to decentralization, to not rely on a single company that produce CHIPS for mining like Bitmain. Maybe will be ok in the future to be more companies to produce ASIC miners.
An easy and quick application for ethereum network is on political branch also. You can create a token for presidential election to vote safe and secure, you can distribute a single unique token to each citizen to send it as a vote for any election and using ether token as a gas for vote.
So, this way gov's can organise elections at a fraction of cost, compared to present budget for organizing elections.
This is just 1 simple application that can be implemented very easy and make political elections be efficient and low cost. I also see ethereum network smart contracts be implemental into medical industry.
Maybe i look way too far into the future, but i believe this is the way we should go with BTC and ETHEREUM.
Sure there are another coins that working better then btc and ether, but the balance between security,decentralization and scalability you can see it only on btc and ether.
Regarding hardforks, i am totally sceptic from technical reasons. Since value of those coins starts with bitcoin ledger history of wallets and coins. If 3mil btc wallets was lost guess what happen with a fork coin history? Right, that coin will produce only few new coins, the early blocks before fork can be accessed only by original Bitcoin holders. Judging by this, the value of the new hardfork coins is basically close to 0. If i fork bitcoin at this moment after 17mil btc was already produced, my new coin will produce only 4 mil coins if i do not change 21mil total amount from bitcoin core, the rest of 17mil coins can be accessed only by the bitcoin users if they will or want.
So, i see forks only as a copy or shortcuts for bitcoin
for temporary use. In a long run term, i am 100% sure forks will go to 0, only time will prove i am right.
