Main question - for long or for speculations?
I think that such issues should be approached fundamentally and guided by what projects I would like to see in the future. For me, it's definitely bitcoin, ethereum, zcash, cardano and 0x. I believe that future projects should be secure, trusted and supported by the community, anonymous and decentralized.
I think same. It's a good choice. I accumulate Cardano and 0x also. And BTC is the main in the portfolio. ETH can show more profitable price as I think
