You barely scratched the surface of what is and/or will be possible with Ethereum. Furthermore, if you lookup which coins can actually compete on the network-effect level with Bitcoin (for example by tracking Ethereum and Bitcoin Meetups like I was doing here: ~~~ embed:ethtrader/comments/4epiks/ethereum_meetups_increase_from_20_to_25_of/) you'll quickly see that Ethereum is not only the ONLY alt coin which is viably competing with total Meetups versus Bitcoin but Ethereum is actually gaining on Bitcoin's Meetups. reddit metadata:fGV0aHRyYWRlcnxodHRwczovL3d3dy5yZWRkaXQuY29tL3IvZXRodHJhZGVyL2NvbW1lbnRzLzRlcGlrcy9ldGhlcmV1bV9tZWV0dXBzX2luY3JlYXNlX2Zyb21fMjBfdG9fMjVfb2YvKSB5b3UnbGwgcXVpY2tseSBzZWUgdGhhdCBFdGhlcmV1bSBpcyBub3Qgb25seSB0aGUgT05MWSBhbHQgY29pbiB3aGljaCBpcyB2aWFibHkgY29tcGV0aW5nIHdpdGggdG90YWwgTWVldHVwcyB2ZXJzdXMgQml0Y29pbiBidXQgRXRoZXJldW0gaXMgYWN0dWFsbHkgZ2FpbmluZyBvbiBCaXRjb2luJ3MgTWVldHVwcy58 ~~~
Also, small MaidSAFE note that you kind of touched upon with "[MaidSAFE] has been a project in development dating back to 2006", but they still have a long long long way to go before they have a working product that the average Joe can use. So I'm sure they'll have plenty of price volatility in the short- to -medium-term however those of you looking to make a big killing off of MAID should go at it with a long, long-term view on it. Basically buy it, hold it and forget it.
Lastly, BitShares is an interesting trade here. They have a fantastically usable trading platform (like x.makerdao.com) and I'm quickly becoming a fan.
