Great post. Had Lisk on my radar for a while. You did put everything in perspective now. The sidechain technology sounds like something ETH would need to implement to take care of their problems.
Will be looking to invest into Lisk shortly.
Also, I have read that the POS algorithm isn't all roses. Yes, it eliminates a lot of wasteful computing, but it is also easier to hack. Looking forward what the future will bring.
