Lets assume the following:

Investor A holds 50000 USD and wants to invest into the following 3 assets for exactly 1 year

-Riskfree rate is 5% (this is way to high obvious)

-Asset 1 = USDbitfnx --> 35% expected return with a SD of 10% (Sharperatio = 3.5)

-Asset 2 = NXT --> 100% expected return with a SD of 50% (Sharperatio = 2)

Also: No shorting is allowed.

He will allocate his funds in the following way, if he wants a return of (with the minimum portfolio variance):

ROI = 10%: RF=43240$ Asset1=6030$ Asset2=730$

ROI = 20%: RF=29723$ Asset1=18095$ Asset2=2180$

ROI = 30%: RF=16206$ Asset1=30159$ Asset2=3633$

ROI = 40%: RF=2688$ Asset1=42223$ Asset2=5087$

ROI = 50%: RF= 0$ Asset1=37500$ Asset2=12500$

Optimal Portfolio of only Asset 1 + Asset 2:

Asset 1: 89.25% Asset 2: 10.75%

This portfolio has a SD of 11% and a expected rate of return of 42%. (Sharperatio = 3.82)

You can clearly see, that under this assumptions the addition of USDbitfnx to the NXT portfolio has an extraordinary reward/risk ratio. Even if you tilt the number to extreme scenarios, you should still add considerable amounts of your portfolio into an asset like USDbitfnx.

Thank you for the attention
