I do not see much difference what platform companies use to switch to blockchain technology and smart contracts. If you are not a developer, it does not matter whether it is Ethereum, waves, Stratis or neo, you will still have to pay minimal fees for transactions.
How can i invest in this industry ?
If you want to invest, I see no problem to invest today in the same projects with their own platforms. (neo, waves, EOS, Ethereum) - they all sank from their highs today by at least 90% and the growth potential is huge!
