Thank you for the thorough answer. I agree and see the problems with both BTC and ETH, but i don't know that they won't be fixed. I think pretty much everyone agree that something needs to happen. But i also think writing them off is a bit premature. Additionally i also think that if end, they will not end with a bang but fizzle out. BTC, because it is the trade coin, and i think lightning will reduce network pressure enough to keep it in that place, ETH is the basis for so many other coins, which i think will keep it going for long.
Thus i think it is reasonable to hold them and bet that they will increase. In my eyes they are the "safe" crypto bet, which is why i like them for portfolio diversification. I think that betting it all on two specific coins like this is a bit risky. At least for me.
I really like the idea of steem even though i don't fully understand it yet. I am still reading up on it.
As for Dash i have a hard time evaluating its merits compared to other "privacy coin" however, the few of their promo videos seem a bit dishonest to me. Then again i don't really understand the premise yet apart from the privacy part. The democratization stuff does sound interesting though.
I have yet to make any serious decision on what coins to back as it is quite the task to evaluate each of them, and just a hobby.
