Hi,
If the Balance was 1 BTC I would only allot 0.25 BTC for investment. Then I would apportion it into different investments.
For example if I was to lend out my Bitcoin I would research the different services available and further divide the amount of Bitcoin into multiple services and diversify again at minimal amounts to borrowers to minimize risk.
I do not mean the entire 0.25 BTC.
1 BTC > 0.25 BTC > What would you do? (Lending, etc.) > Diversify > Diversify and Minimize.
