With Bitcoin BU getting more and more support from miners lately, I'm looking for good coins to hedge against the uncertainty of a hard fork. Any suggestions for coins that qualify?
Imho the best coin for your problem is Bitcoin. Yes, I mean that you should not buy altcoins if you don't really want to.
If the hardfork will happen at all, you will end up with BTC + BU (if your money is in a local/proper wallet).
Whether the hardfork will happen or not, the "winning" coin will come back to this value and even higher.
Whether the hardfork will happen or not, the altcoins market has a lot of uncertainty too, since they are bought for Bitcoin too.
