First read our opus on XRB, Raiblocks...

Then realize there's a catalyst in the future Binance listing.
Like it a lot better than Iota, altho we haven't fully explored Iota, it just sounds like it's going to take too much time. But then again, Ether rocketed well before anything was really built on it, so maybe we have it backwards?

2nd theme: ETH and NEO over BTC
Ether's platform SHOULD begin to prove itself in 2018, which could then bring back the talk of it overtaking bitcoin. in any case, we view Ethereum as much more interesting bc of what's brewing in the community (like ERC-20 based exchanges which are private)

ZRX: Love it, should be a big theme this year, any decentralized exchanges will be a big hit in 2018, as Binance now rules the roost but those on older exchanges should begin migration.

Prefer BTS over Eos, is anything on Eos yet? BTS at least has a working exchange.

Don't like your reasoning on Ark whatsoever, never buy for a dividend. that said, it's another crypto we don't know much about, but if all it is, is a platform, blehhh

Really like Neo for it's potential add to BitFlyer and Stellar for its possible inclusion on Coinbase. But Raiblocks has them both trumped bc it just went down for a very poor reason with the BitGrail (manipulation?) situation.

We are stuck in Steem tho, which we actually think might be the best of them all. So maybe it's a good thing we don't have a trading account, but that doesn't stop us from transferring our extensive experience in stocks and bubble-markets into crypto-ideas, short, medium (catalyst-based), and long term.

Again, check out our Raiblocks post, might shed a new light on it both catalyst-based (see comments) and for longer term competitive aspect to bitcoin which we think is heavily flawed and far too ensconced with government at this point. Who runs bitcoin now, the ghost of Satoshi or Nancy Pelosi and Donald Trump?
