I put most of my money in NEO as my crypto-bank.
This is since NEO pays me a generous 4 to 6 %/year worth in terms of NeoGAS + it is pretty stable and its price is expect to only get stronger into 2018.
ETH is a safe bet, however there is a war brewing against the ETC community making it unstable + any significant improvement on it will be slow due to the already large user-base (demanding backward-compatibility + consensus amongst miners). Also due to its already very high MCAP, the %Gain possible is so much lower than what NEO can easily accomplish (given the same amount of new investors injection of funds).
VeChain will be doing the same soon once the VEN token gets linked to their new "Thor" coupled currency.
There are some ppl who are speculating on NeoGAS as a much better buy in the shorter term than NEO, as the demand for GAS will skyrocket as more NEO-based ICO pops up; while NEO's value (the stock issued that generates GAS) will increase significant as the amount in circulation reaches its max supply.
Also I do not trust the WAVEs team, and had sold all my waves coins after finding out that they have plagiarized code from the super hardworking and capable Cardano team of PhDs w/o even crediting them. Also the very need of Wave's team to use other team's codes do not speak well of their own ability to innovate and competence IMO.
Source to the plagiarizing allegation? Waves has been around far longer than Cardano so I'd be surprised if that was true. Not that it would be very relevant.
