There's not an equivalent to mutuals in the cryptoverse yet, but there will be.
I've made quite a few small bets on various alts. I'm taking the black swan approach to them. Quite a few could drop to zero in a couple years but I'm betting at least one of them will make enough of a profit to eclipse my losses in the others. If one of them had been Raiblocks, that already would have been the case ($0.10 cents to $34 in 3 months...crazy). It missed my radar because the aggregate site I check didn't include it.
