Agreed, it is not necessarily the best, it is just the strategy I am employing for now. I have extensive experience with the similar beta profile mining stocks. Currently with those, I see no reason to invest in the really speculative exploration companies when the better mid size miners are so undervalued.
Maybe I am letting that strategy cloud my thought in the crypto world, but I think the gains in the better cryptos for me will be satisfactory for now. I do really like your point about the Ethereum based plays. I will look into that more carefully, thank you for pointing that out.
