RE: IOTA will not last because it will not get collectively adopted.
Thanks @valderrama for posting the link to your take as a reply on my article (https://steemit.com/iota/@playforpleasure/iota-has-gone-down-like-i-predicted) I had already read a part of it and I think it's really interesting to think about. I get your point about big companies wanting to build their own blockchain, IOTA wants to connect different devices designed by different companies. So I really hope IOTA will work out because I think in that way the interactions could be way more streamlined. But I think you're absolutely right about the big companies wanting to develop their own systems. IOTA doesn't use a Blockchain it uses the Tangle, but I think you already knew that and just wrote Blockchain for the convience for people to make it more understandable:)
What's your take on Ethereum?
Thanks for your Tangle remark, I knew, I forgot. Edited my post ;)
My take on Ethereum? Well... defintately a good long term investment. Not much risk involved. But... there is a scenario that I can see happening where they will loose their number 2 spot. I've written about it in: https://steemit.com/cryptocurrency/@valderrama/will-stratis-overtake-ethereum
And in: https://steemit.com/cryptocurrency/@valderrama/stratis-will-beat-ethereum-in-2018
Perhaps a little provocative but it can happen.
