Thanks for the great reply! That's a lot to think about. There are so many future scenario's for cryptocurrencies. I guess the key is to diversify your holdings, and keep an eye out for the signs you described in your post.
edit: By the way, I loved you analysis of Ripple and Ethereum posts!
Glad to hear it! I will be covering some ICO's that may be interesting, exchanges that will help you get them first, and of course, the markets as they change - like my Litecoin(LTC) article, which unfortunately only gave my followers a 12 hour window to invest prior the price jumps.
