I'm following this interesting project for sometime. While I have my own trading and investing strategy I agree with Frank regarding Bitcoin but I'm not sure about ETH. It has more scaling issues than Bitcoin. Despite that ETH was strengthened by many attacks on the project, so there is room for better results. But I still think that ETH is not suitable as a global TX network. I will go with NEM for that.
True, with current state ETH also may have scaling issues in 1-2 years. Difference is that ETH has a strong leadership that can execute fast the scaling solution they believe oportune, while BTC will be stuck in the same debate for a long time. One can say that this means that ETH is more centralized than BTC. True, but the big money is going to ETH, and will keep going to ETH, so it would be foolish to ignore that and not profit from this situation. We have to remember that ETH token value represents the entire Ethereum network, and it has the potential to be much much bigger than BTC network.
