all of cryptocurrency is shitcoin..? bitcoin too..?
etherum is altcoin but the technology behind it is good, it's diffirent with paycoin.
Databases are great, you can embed them everywhere like within your browser for quick access to local data. Big databases need big storage. Facebook needs lots of servers and the data is replicated at least twice so there is no single point of failure.
The so-called massive feature of Etherum is you can stick data in the blockchain and then everyone has a copy of it so you have built in reliability. Of course if you make a change to the database, you have to write the whole thing back again to the blockchain. The original still exists but you now have a new copy and the old copy will sit there forever, not being used by anyone, but anyone that uses the blockchain has to download and verify this useless data. If this so called great feature too off then the blockchain would become supper massive super quick and would inevitably lead to Etherum's death as the block chain grows exponentially.
So the great feature of Etherum is it has this great api that if people actually used will kill the coin.
The other thing I keep hearing is how banks are interested in using this. Well yes they are but banks just want to make sure that there own ledgers are secure and they would probably do that by having their own type of blockchain computing keys for subsets of data to ensure that the data hasn't been changed. This does not mean that banks want to use ethereum/bitcoin or other crap. It means they just want to use bits that they might re-purpose for their own uses.
Every coin seems to need a genuine reason to convince people that they need to invest in it. (Invest=pay money to developers/scammers).
Paycoin=guaranteed floor
Etherum=Apps in the blockchain bullshit
Ionomy=Gaming currency. (Another currency targeted at a certain market. If I go shopping I don't want to pay for beer with one currency, meat in another, etc etc)
tl:dr; If you believe in etherum or any altcoin you've been conned Muggles
Real question is does btc have a future? And if you've ever invested in an altcoin you don't deserve to have a view on this.
