i have found these article that distinguish between bitcoin and ethereum
unfortunately articles like this are written to advertise ethereum so they are ignoring all the faults of it.
while Ethereum’s aims to be 12 seconds. A faster block time means that confirmations are quicker.
that also means ethereum is creating 50x more blocks than bitcoin and as a result its blockchain has been growing alarmingly fast. i don't know how big it is now but last time i checked it is orders of magnitude bigger than bitcoin's blockchain and some say it will reach 1 TB soon. and bitcoin has ~150 GB blockchain now.
what this means is that you can no longer sync your ethereum wallet with the network unless you use third parties for example using a web wallet. this effectively centralizes the network.
Ethereum raised its launch capital with a presale and only about half of its coins will have been mined by its fifth year of existence.
there is no cap for ETH so you can not say "half of it" because unlimited can not be halved
current supplies are:
BTC: 16,950,000 (max = 21,000,000)
ETH: 98,542,000 (max = infinity)
Ethereum rewards miners based on its proof-of-work algorithm called Ethash, with 5 ether given for each block.
if i am not mistaken ETH reward is also halved. it was reduced anyways and it is currently at 3.
but the important difference is in total daily new coins created:
BTC: 1800 coin/day
ETH: 7200 coin/day
Ethash is a memory hard hashing algorithm, which encourages decentralized mining by individuals, rather than the use of more centralized ASICs as with Bitcoin.
you can't use bitcoin's ASICs to mine ETH but that doesn't mean no ASIC can ever be created to mine ETH! they can simply modify the mining equipment they are producing to match ethereum's hashing algo and mine it with new versions of ASIC. so far nobody has started production because they fear the centralized ETH dev team change the algo at any moment and ruin their business.
Bitcoin and Ethereum also cost their transactions in different ways. In Ethereum, it is called Gas, and the costing of transactions depends on their storage needs, complexity and bandwidth usage. In Bitcoin, the transactions are limited by the block size and they compete equally with each other.
fees in both cases is somewhat deepening on the size. but since ETH is basically smart contract platform it is calculating the fee based on the complexity of the execution of that smart contract which will basically increase as the size of the transaction increases.
the number of investors with bitcoin, the price of it since it has many investors so we could expect expensive price of bitcoin compared to ethereum. Investors has put confidence and trust with the system. Bitcoin has hold the world record and it has hard to surpass with the record holding by bitcoin.
it is not without reason!
more demand (ie more investors) in bitcoin is because of its usefulness. bitcoin is acting as a currency for real and that creates demand.
