I still see lots of posts about bitcoin, bitcoin mining, and so on. I've even got a little lotto mining thing going myself. Although I've probably got more chance of winning EuroMillions Lotto.
Obviously Bitcoin isn't going away - but mining for it has long gone for anyone but government sized corporations. So why is anyone bothering with it. Like actual Gold - it's just not worth being out in the hot sun to try and find... Just like Gold - if I want it, I'll just have to buy it. And why would I bother.
 
So give me one good reason why I'd want to buy Bitcoin?

The main players I see out there now are Blockchain.info and Coinbase.com
Of course there are dozens of other players, but it looks mighty like those two are the top players in the Bitcoin field. I know I'll be corrected on this, but that's what it looks like to me.

The Other Player that seems to be gaining ever more traction is the Ethereum parties. The ethereum-wallet people, and so on.
Is it too late to bother with Ethereum as well? Is it even worth mining the Ethereum?
https://www.ethereum.org .... Interesting site. But again, I don't see much recent activity around it. Not since mid 2015. Like Bitcoin, it works, the site that is, and the wallet app etc, but to what end.

Has Ethereum gone the way of Bitcoin? Taken over by ... the banks? and Big Business.

It's all looking like a big fat waste of time - as people keep telling me. If all I can now do is Buy Bitcoin, or Buy Ethereum and store it in my wallet, then use it for coffee or gambling, or in a few pubs, then whats the point?

What am I missing here?
