So many Cryptos, so little Fiats- If you are going to invest then...

I'm a little concerned today. I read a post from 8 months ago by intelliguy https://steemit.com/beyondbitcoin/@intelliguy/one-thing-satoshi-nakamoto-underestimated-was-greed-we-underestimate-it-too-let-s-correct-our-mistake
In it he states that there were 653 crypto currencies, Today there are 752 according to https://coinmarketcap.com/all/views/all/

So I continued my research and came upon this little gem of advice from Fitz Tepper, and I felt it applied directly to Steem. "... if you’re going to buy cryptocurrency, do it because you see the long-term vision (and sure, ostensibly the financial gains that may come from them), not because you think it will blindly appreciate and give you a good return on your “investment.” full article here https://techcrunch.com/2017/06/07/what-the-hell-is-happening-to-cryptocurrency-valuations/
