Is 40% to 70% allocation an Over-allocation into BTC?
I believe that my current allocation into BTC is about 75%
Yep basically thats how becoming over balanced would work out. I generally say 1% in gold helps alot, its heavy it counter balances alot :p but most people over estimate their free capital. By free I mean you have it to save for like ten years as capital not money before a bill comes due.
Some dont subscribe to the idea of capital allocation and balancing so thats really upto the individual. Taking more risky routes could pay off but the point is to avoid the risk, also thats losing some of the gains quite possibly.
If you go younger, in the 40-50 yr old range, you find a lot of guys that are just flat out hostile towards Bitcoin, like it threatens their very way of life or something. You should of heard the vitriol that my (former) Accountant was spewing about Bitcoin in 2013.
Why isnt that same person just as angry about bad accounting by central government. The never ending monetary base expansion is self bias, since I dont operate in billions Im worse off from 'being outside'. Do we all believe government can perfectly distribute this new money, of course it doesnt do so.
Heres a good link I saw that I think explains about how USD self funding works and inversely why Bitcoin is in demand as unbiased to a central point of failure (not that I think any system can be perfect not even gold

)

Almost anyone can buy a gram gold. In many places its tax free, compared to the lost freedoms after ww2 we do have that going for us now. Most dont realise gold is not especially expensive (unless you also believe oil will be going down by half long term ) missing the above effect which is increasing as QE unravels.

BTC is wavering on the first rung of the ladder above the previous low, in April. Not sure what to take from that except its likely forming a longer term move
