Crypto and bitcoin have had a wild run the past year. I've been investing for the past 20 years and speculating on cryptos since 2014. Although I think Bitcoin will regain dominance in the near-term, I've positioned my spec fund the following way:
From largest to smallest holdings:
BTC - seems pretty boring compared to the other stuff out there, but I agree with the Cryptovestor Steemit guy that it probably gains dominance back in the near term after a long consolidation phase. He writes some good stuff but is probably not aggressive enough in this sort of bubble. My guess is that because he was burned by the dot-com boom he is more cautious this round.
ETH + large alt coins. Holding much more ETH and then small, equal-weighted positions in ADA, XLM, OMG, ZRX, KNC, BNB, VEN, ICX. A lot of these (ADA) are nothing-burgers and other ones (XLM) are inflationary. Some (TRX, IOTA) might be scams, which is why I'm not buying them. The rest are probably overvalued. But hey, Google paying $1+ billion for YouTube back in the day also seemed insane.
A portfolio of 15 very small positions in what polite company would call a "low-priced fund." (Hey, Fidelity has a long-running "low-priced stock fund" which I never understood the point of until now.) Basically the inspiration of this came from my technician who said that lots of folks are buying cheap priced crap because they don't understand market cap and just buy on price. So this fund has lots of stuff that is less than $1/coin.
