Given the facts, I think it really boils down to your preferences either for short-term or long-term investments. Do remember that each type of investments has their own set of risks to consider. For example, bonds may be the most secured type of investment due to its nature being on the bank but profit wise, it might be longer.
On the other hand, bitcoin may yield you the highest profit but the security of payment is not secured compared to the others.
Personally, I would half my investments into two, like one for bonds and the other for bitcoins for safety purposes but if you plan for long-term then bitcoin is the way to go.
