It could be a little bit technical and engineering, but I have been doing some research on the features of the block chains, so I'm leaving a note of what I think about the value of the block chain platforms.
Well, Bitcoin is already well known, and the price has already risen so much that it is really a matter of investing or not, and it has become a situation where you have to go according to the so-called market logic.
The limit of Bitcoin is less scalable than other cryptocurrencies. Of course, since the emerging platforms complemented the disadvantage of Bitcoin, I don't think there is any guarantee that the future value of Bitcoin will remain as it is now.
However, if Bitcoin is used as a pronoun representing the cryptocurrency, it will be a different story if it is politically or socially designated as the official currency of any organization or country.
Ethereum, on the other hand, is the most popular block chain platform since Bitcoin. (Of course, the number of block chain systems is now so much.)
Because Ethereum has the advantage of being able to add custom functionality to smart contracts (which is a fascinating feature for developers), as it expresses service concepts like dApp so that service developers can easily use the block chain system, the ability to store larger size custom data than Bitcoins, etc., are already well known, and are also gaining popularity in the cryptocurrency market.
Perhaps, for now, Ethereum has been built on a number of services and applications from around the world, and from now on, its value is likely to be quite high over time, or even higher.
I am careful, but I also think that things that are much more valuable than Bitcoin will happen.
And ERC20 which is led by Ethereum is becoming almost standard protocol of cryptocurrency, and the new version of Ethereum is under development ...
On the other hand, like the phenomenon caused by CryptoKitties last year, the biggest problem is that the number of transients processed per second is small, which is too slow in a word. (This is not a matter of only Ethereum because Bitcoin is also slow too.)
But this year, there is a block chain system that is getting more attention than the one that is growing in this spotlight. That's EOS.
Of course, you can see a lot of things after the official launch of EOS this June, but I think Dan Larimer's strategy is smart. EOS may be ERC20 compliant, ICO on Ethereum, and the adoption of DPOS algorithm at a limited number of nodes that can improve speed, in fact, it is likely that it may exceed current limit of Ethereum.
Of course, you will have to look at issues such as security after its official opening, a small number of note authentication methods (DPOS with small number of nodes) can be a security problem, the level of smart contract support, etc.
The debate between Ethereum's Vitalik and EOS' Dan in last year (2017) was a big issue (https://cointelegraph.com/news/ethereum-vs-eos-shots-fired-on-reddit-as-vitalik- dan-larimer-clash) I think this argument actually helped to develop the EOS.
Because, I guess, Dan would have been more concerned about Vitalik's comments or even worrying about not receiving any more of these attacks while developing EOS.
In summary, the value (price) can be summarized as follows: 1. The value of Bitcoin appears to depend on market logic, political and social logic, 2. Ethereum can increase in value, 3. it seems that the price of EOS is likely to soar.
