Putting it all in ETH doesn't make sense and holding a ton of BTC on August 1 could potentially be a bad idea (depending on who you ask).
Unfortunately I feel like a drop in Bitcoin's price would hurt all cryptocurrencies, so I'm just HODLing my BTC and hoping it skyrockets instead of dropping...
My guess is that BTC will drop (perhaps a lot) while all the forkings play out, at first. All the confusion means "uncertainty" and markets HATE uncertainty.
Then once whatever "clear winner" emerges (may take a while) we will see a huge spike UP, perhaps even one of those long-overdue 10X runs that HoneyBadger's been famous for in the past (a penny to a dime, dime to a dollar, dollar to $10, $10 to $100...)
We've just barely left that long-time, extended "$100 to $1000" era here now at "only" $2500 which is "only" approximately a measly doubling... once the long-overdue "Scaling Debate" ANSWER is *finally* decided, one way or the other, SegWit or LargeBlocks or what-the-fuck-EVER... maybe THEN we can *finally* see the next era of $1000 to $10,000 *finally* kick in!!!
Or maybe the forkings will just destroy bitcoin entirely.
So $10,000+ MOON or $0 FAIL binary outcome? Same as it ever was...
