That’s not true. Those things are not needed with PoS and PoI blockchains.
Their website states:
Is the Electroneum team living in 2009 or 2017? Or, are they trying to scam newbies into thinking that Bitcoin is the only crypto currency that exists? There are many crypto currencies already that provide privacy, such as Monero, PIVX and Zcash.
Mobile? Lots of altcoins can be on the phone. Offline wallet? This is when Electroneum is deliberately misleading or lying. They state:
Are they trying to make you think that there are no offline wallets for Bitcoin and Ethereum? There are LOTS of them.

So, what’s so special about Electroneum? You already have a multitude of crypto currencies on your phones today.
Spectivvr.com’s white paper has only one problem that they are trying to solve. Their write up of the problem is less than one page and is one of the weakest and most nebulous problems I’ve ever read. I have no idea why a new crypto is needed.
If Spectivvr.com is trying to put virtual reality onto the blockchain, then it shows that they are clueless about the blockchain and that they have never run Bitcoin’s full node. ARToken wants to put 3D data onto a blockchain. This implies hundreds of Terabytes of data. Bitcoin’s blockchain is 120 GB and Ethereum’s blockhain is 200 GB and they are both having scaling problems.
Their business model is given in one sentence:
How are they going to compete against Youtube, which already provides 4k videos? What’s to stop Youtube from providing virtual reality videos? How many viewers are going to go through the hassle of buying Spec tokens just to tip video producers, when they don’t have to do that now on Youtube?
