Waoh never thought of this
also the size of the blockchain will grow 4 times faster in other words bitcoin blockchain size after 9 years is about 144 GB and BTX in 4 years could have 576 GB which is huge.
Kinda impress with your sharing
But why would ETH not last long in your case? I assumed ETH is kinda a good Bitcoin alternatives to replace it if we doesn't have coins like NEO, Waves, EOS
whatever ETH is, it is NOT a bitcoin alternative because they are not in the same category. bitcoin is a currency made to perform as a global payment system while ethereum is a platform made to perform as a blockchain for smart contracts.
when you are making a distributed ledger and claim to be decentralized you have to consider the fact that regular users have to be able to run the full node and store that distributed ledger so that you can have a perfectly decentralized system.
when the size of the whole blockchain is gigantic (above 1 TB for ethereum right now) and the average user doesn't have that much space to waste for the blockchain (it is 140 GB for bitcoin) they end up using third party services like MEW and after a while only a handful of people (usually exchanges and the foundation) run a node and that is the source of centralization because from then on you have to connect to that centralized node and push your transaction and they can easily deny your tx, ask for more money (bribe), change anything they want in the protocol,... meaning full centralization.
and it is not just about the size it is all the other resources that it takes. like your RAM to load the large data in it, all the CPU power it takes to verify the blocks, relay transactions, ... all the internet traffic that it takes so unless you are on a no-cap internet you will waste a lot of your traffic running a node and a lot more.
