I agree Eth has great potential but also has to work out some scaling issues. I like Dash as well, doing a great job marketing which is huge in this space. The reason I mention digibyte is due to its security. I always try to keep a percentage of my hodlings in a ultra secure coin. Especially after what happened with zencash. I have a feeling that will not be the last major 51% attack. Hodling platform projects is key but they aren't always as secure as multi-algo projects.
Another great multi-algo coin that has tons of potential is Unitus. I’ve been accumulating Unitus for a while now. No ICO, No Pre-mine and No dev tax. 5 algo’s, all merge mineable which allows the miner to get rewards from two projects at the same time while only using the energy of mining one. You can mine it with CPU/GPU/ASIC without the ASIC’s having an unfair advantage. You can even mine with a cell phone. One of the best features will be a hybrid proof of work/proof of stake system that will be implemented in 2018, which will allow hodlers to earn block rewards for hodling. Their circulating supply is only 58 million, it will hit its soft cap of 83 million in June of 2022. Afterwards block rewards will stay at 2 UIS.
